How to refine a Denim Sheath Skirt look


In this posting I share some of the fitting and sewing techniques I used to refine my favorite denim sheath skirt. The skirt is made with a bottom weight 100% cotton denim by Kauffman. The fabric was laundered and dried prior to marking, cutting and sewing.

The pattern was developed entirely through draping in cotton muslin.

The skirt had several parts of the construction done by hand. The blouse was purchased online.

Fit is Everything!

To give the skirt more style ease I had to add extra width at waist, hip and hemline. Some sewing books say extra width can be added at the side seam. I found that it is better to open the pattern between the second dart and the side seam. You measure the mid-way point between the dart and the side seam. Draw a vertical line from waist to hem. Then open 1/4 of the total amount of style ease needed. This alteration is the same for front and back of the basic sheath skirt pattern.

In the photo of the back pattern piece for the skirt you can see the place where the cut was made and extra paper added to the pattern between the second dart and the side seam.

Note: The pattern for the skirt was made using Precision Draping by Nellie Weymouth Link. I gained weight since the time the original drape and pattern was made. This necessitated the need for the alteration.

Dressmaker Finishes for a Refined Look

A slot zipper application was used. I followed the hand sewing technique detailed in Couture Sewing by Claire Schaeffer. Instead of using a prick stitch or back stitch, the zipper is sewed into the seam using tiny running stitches. To further secure the zipper in place, the zipper tape is fell stitched only to the side seams, at the edges. The zipper stop is covered by a lightweight piece of lining fabric. I used a small piece of lace hem tape instead.

A kick pleat with insert was made back seam. It provides ease of movement as well as a finishing touch. The top of the kick pleat is stitched into place using a triangular shape. A kick pleat is more refined than a high slit at center back of the skirt. That is why this skirt works well for casual dress days at work or an outside meeting with business associates.

All seams were pinked and then edge stitched. Wrights Flexi-Lace tape provided a finish for the hem and kickpleat.

How to draft a Sheath Skirt Sloper

These pattern drafting instructions were given to me by a student who attended the Traphagen School of Design in the 1980s. It was a private design school in New York City. The instructions are very simple when you take the time to read them through before you start drafting your pattern. Make a muslin to test the fit before using this as the basis pattern for any pencil skirts or other designs based on the basic skirt sloper. The basic sheath skirt (a/k/a pencil skirt, slim skirt, wiggle skirt) has not changed. This pattern can serve as a sloper for vintage or modern skirt designs.

Measurements Needed

Center Back Length (from center back waist to desired length of skirt)
Center Front Length (from center front waist to desired length of skirt)
Back waist measure (from side to side seam at back)
Front Waist Measure (from side to side seam at front)
Hip Measurement – 7 to 9 inches below waist-use widest circumference.  Add 2″ of ease to measurement.
Lower Edge of Skirt (this measurement is determined by the hip circumference plus 2″ ease

Important Note:  Look at the complete diagram.  The rectangle runs from point A back to point A front at waistline.  Point B back runs to point B front.  Point A to B in the back and Point A to B in the front is the skirt length.  I found it easier to start with a large rectangle where A-A and B-B equals the complete hip measurement plus 2 inches of ease.  So draw A-A for the waist.  The draw A to B for center back.  Draw B to B for lower edge.  Then from B in lower edge of front draw a straight line up to A front.

Then proceed to step 2.

1.   Draw a line from A to B equal to desired length of skirt measurement.

2.   Square a line up from A and B equal to 1/2 ofequal to 1/2 of B (lower edge) and mark center C.

3.   A to D is 7 to 9 inches below waistline.  This is the hipline level.  Connect D on center back to D on center front.  Mark Center E. 

4.   Measure from point A at center back to 1/2 of back wait measurement plus 1 1/2 inches for two waistline darts.  Mark point F.

5.   Measure from point A at center front to 1/2 of front waist measurement plus 1 1/2 inches for two waistline darts.  Mark point F.

6..   Square a line up 1/2 inch from point F to G on both front and back.  Mark point G. 

7.   Shape curve of hip from point E to G on back and front.

8.   Shape front waistline from A to G.  Shape back waistline from A to G.

9.   Plan the position for a 3/4″ wide dart to correspond with the waistline dart position of the back bodice*.  Make dart 6 inches long.

10.   Plan the position for the second dart 3/4″ wide and 5 inches long.  This dart should be the center from the end of the first dart and the side seam at the waistline.

11.   Plan the position for a 3/4 inch wide dart to correspnd with the waistline dart position of the front bodice*.  Make dart 4 1/2″ long.

12.  Plan the position for the second dart 3/4 wide and 4 inches lont.  This dart should be the center from the end of the first dart and the side seam at the front waistline.

13.   Cut out sloper.  This sloper must have 1/2″ seam allowances added at waistline, side seams and center back.  Add hem allowance at bottom of skirt.  The hem for the basic skirt is usually 2″

Photos of me wearing the Pat Perkins 1950s dress and my 2021 version

Please note: I forgot to button the second button on the Alice Elizabeth dress when putting it on for the photo. Also my version of the dress was created for a Misses Size 8. I did not alter the pattern or the dress because this is part of my portfolio, not my personal wardrobe.

The Pat Perkins dress is a little short in the waist for me. otherwise the fit is very good. There is a 2″ style ease at the waistlisne which makes putting on the dress very easy. I wore the dress all morning and found the side zipper did not bother me at all. Going forward, I will use a lapped zipper in he side seam for my next 1950s style dress. I think I made too much work for myself going with snaps from waist to knee.

The side seam zipper lies flat. It does not affect the hip line or bodice side seam. I think this is because the fabric is a lightweight cotton. This was an amazing purchase, The dress is in such good condition. I feel so fortunate to have it both to wear and use as a study piece for learning more about vintage garment construction.

Alice Elizabeth: My version of a 1950s House Dress by Pat Perkins


The dress pattern and design is based on a 1950s house dress by Pat Perkins that I bought during Lockdown 2020. I wanted to create a basic pattern to dervice this and future retro inspired clothes I make. I bought the dress from a vintage seller on Etsy and posted a detailed style analysis . I had plenty of time during lockdown to learn about different vintage draping and patternmaking systems. I chose to teach myself Precision Draping from the book of the same title by Nellie Weymouth Link.

After draping the basic toile on a 2019 Misses Size 8 Wolf Form, I created a sloper on oaktag. I released this sloper into the public domain for anyone to use and improve on. This sloper is the basis of the pattern for the Alice Elizabeth dress.

Dress and Pattern Details

The dress consists of a fitted bodice with two vertical dart tucks on each side of the bodice in front. The skirt is six gores with a very moderate flare at the bottom. The Pat Perkins dress has buttons and loop closure down center front. A metal zipper was sewn into the left seam from 2″ under the arm until the hip line using a lapped application.

I do not like side seam zippers for two reasons. First they can be uncomfortable. Second they interfere with the flow of the underarm seam and skirt side seam. Since fitted clothing often falls on the bias at the side seams the potential for distortion exists. I hand sewed six button holes in the front of the bodice.

My reasons for avoiding buttonholes on the entire dress is that it would spoil the look of simplicity and efficiency the house dress is supposed to convey. I had not thought about using a hidden zipper when the dress was in progress. Now that it is finished I have a hidden zipper in mind for the future. It is a simple application I will detail when it is in progress. I used snaps because the front portion of the skirt looks better. The eye is drawn upwards to focus on the striped buttons and self-fabric belt. I do not care for metal eyelets and prongs in a belt so I used snaps to fasten the belt.

The edge of the front facing, the waistline stay and hem were finished with navy blue Flexi-Lace by Wrights. Seams were pinked. I chose these finishes because they are similar to home based seamstresses used in the 1950s. The Flexi-Lace tape was completely stitched by hand to the waistline seam using a running stitch at the waist and edge for flexibility. I used a cross-hatch stitch to join the stay to side seams and dart tucks.

The dress is made from 100% cotton chambray. It is very soft with a good drape. To support the dart tucks more a small edge stitching was used.

A back yoke was used to eliminate the neckline dart on the basic back bodice pattern. That too was edge stitch. On the inside, the yoke is interfaced and lined. The dart tucks in the back are also top stitched.

The collar is a basic collar pattern with a high stand. The undercollar and interfacing are cut on the bias. The sleeves have all-in-one cuffs.


I chose understated accessories in sterling silver to keep to the everyday quality I want this outfit to have. The earrings have a pretty filigree. A small silver necklace, about 16″ long, with tiny beads would also look good with this dress.

Ballerina flats in navy blue complete the outfit. They pick up on the color of the stripes on the buttons. The overall impression of this outfit is meant to make the wearer attractive in a modest, understated fashion just as house dresses were intended in the 1950s.

Misses Size 8 Slopers you may copy and use

I am releasing my Misses size 8 slopers into the commons. I grant permission to anyone who wants to use them commercially or personally. You can copy, download and size in your graphics program. My reason for making these available is to help others get a head start on their patternmaking and dressmaking business or hobby. The slopers were developed through draping on a Misses size 8 Wolf form. The grid used for the photos is in inches.

New Dress “Alice”: Progress Photos 2-6-21


In this posting I share progress photos of a new dress developed through a combo of flat patternmaking and draping. The photos featured are of the half-toile to test the fit.

Combination Technique: Draping and flat patternmaking

95% of this toile was made using a flat pattern. I used the Misses Size 8 sloper to create the fitted bodice, semi-fitted skirt and basic unfitted sleeve.

3/4 view of half-toile.

The flat pattern for the bodice front had the horizontal side dart closed and vertical dart opened. The construction of the bodice shoulder, back yoke, back tuck and side seams were completed. After steam pressing the bodice was pinned to the form. The excess dart intake below the bust was draped into two vertical tucks each 3 1/8″ high and about 1 1/2″ wide. I like the softer look of the tucks over the dressmaker dart under the bust.

Front view of half-toile..

I am very pleased so far with the 6 gore skirt. It was created by closing the darts of the basic semi-fitted skirt. The skirt front and back were cut along the lines of the dart and below the dart. Each piece then had extra width added at the hemline along front and back princess lines and side seams. I find the fit of this kind of gored skirt even more flattering than that of the 6 or 8 gore skirt created through flat patternmaking.

The collar was simple, easy flat patternmaking as was the sleeve. The next posting will be published once the fitting toile is complete.

Giving a Name to the Dress

As I work on a new project and gather the notions and fabric, I develop an image of who the dress will be for. I choose a name to create a sense of space between my self and what is coming to expression. This permits me to think whether or not improvements are needed. When I am too close personally and emotionally to a project become too attached. That is not good because it prevents perception of where the fit or creative result is lacking. This dress is called Alice. I will add a middle name once I feel more of the character of the dress emerging.

Marfy “Evergreen” Edition

The Marfy pattern books are published by Marfy Studio Stilistico in Ferrara, Italy. Each edition comes with a free, multi-sized pattern. The illustrations are detailed enough so that dressmakers and patternmakers can get ideas for their own projects.

Along with the exquisite illustrations, there are fabric recommendations. The color combinations are sometimes striking, other times subdued. There is something for every style preference. The illustrations include jewelry, shoes, hats, handbags that complete all the must know details to create your own version of the look.

I recently bought the “Evergreen” collection catalogue. It includes Marfy pattern illustrations from the past and the present. There is a wide variety of looks from evening wear to casual wear. Many outfits consist of skirts, slacks, blouses and a various styles of coats and jackets. The lines are simple which make for a look that will last beyond current trends.

Pat Perkins Everyday Dress, circa 1950s – Analysis


Further consideration of my plans for my next project is needed. The sketch of the chambray shirtwaist dress expresses my idea. However, the details I had envisioned must be changed.

I had planned on having in-seam buttonholes. I have been wanting to try this kind of buttonhole for a long time. I want to see how it will work on light to medium weight fabrics. As I thought about my shirtwaist dress I can see that having a seam along center front will cut into the middle gore of the skirt front. This will add extra weight and interfere with the flare. I plan a six gore skirt for the dress.

Possible solutions for new design details

I decided to analyze the construction details of a Pat Perkins everyday dress I bought on Etsy. Pat Perkins was the name of a dress manufacturer in the 1950s. They provided some of the dresses worn by actress Audrey Meadows in a popular sitcom, “The Honeymooners”.

I found the solution to keeping the flares of the skirt undisturbed. I will have to install a lapped zipper into the side seam. I will use the same treatment as used in the Pat Perkins dress. This means I can use in-seam buttonholes for the dress. However, the buttons will only be used on the bodice. Having a size zipper will provide the means for ease in putting the dress on or off.

Pat Perkins Everyday Dress circa 1950s

The dress has a fitted bodice with two vertical tucks on each side at the front. The short, unfitted sleeves have a self cuff that turns up from the inside. The collar is similar to a blouse collar and has very little stand. The back bodice has two very small tucks on each side.

The skirt i seven gores: 4 in front and 3 in back. There is a slight flare in each panel. The panel at center front has a seam. At the back there is no seam in the center skirt panel.

To make the dress easy to put on and off, there is about 3″ of style ease at the waist. The fit near the chest and bust has a little less style ease. This will help me adjust my pattern after using the sloper to trace the basic pattern.

The zipper is machine stitched into the left side seam. There is an underlap of fabric that provides body for the zipper and protects the wearer from feeling the zipper teeth. I plan to do the zipper application by hand and use a lightweight nylon zipper. The one in the original dress is metal.

The dress closes with self fabric button loops at center front. An underlap on the left side of the front bodice provides support.

The belt holes are not reinforced with any stitching. No eyelets were used. The buckle is covered with the fashion fabric. Narrow loops at the side seams are the only support to hold the belt in place. The backing has the stamp “Belt King”. I plan to use a belt kit and eyelets. At the side seams I usually use thread loops.

To lend a touch of support to the back of the dress a long facing is used as part of the collar treatment. I do not plan to use this neckline finishing since my dress will have a yoke.

The seams are not finished. No pinking, no edge stitching. The waistline seam is pressed down rather than up. The hem was turned twice and looks to be hand finished.

Standard Misses 8 and my Altered Customized Sloper


The basic fitting shell for the Misses Size 8 was draped. A toile was made twice each time refining the fit. When the basic Size 8 was turned into a sloper I then went on to customize it for myself.

Why not draft a custom made pattern?

I have been drafting patterns to my own measurements and have become very comfortable with the system I use. During the COVID-19 related furlough from my job this past Spring I decided it was time to take on a few challenges.

I am weak in the making of alterations. Since my dress form is a standard Misses 8, I decided to take on the challenges of draping and altering a Misses 8 for myself. I am between a Misses 6 and 8 for the bodice. For a skirt I am between a Misses 8 and 10.

I also have fitting challenges resulting from a small bustline, concave chestline and sloping shoulders. There were a few challenges I wanted to take up on the time I had to stay home from March until June 2020.

Working with Oaktag

The goal of using sloper was on my To Do list since 2018. The large roll of oaktag I bought from Steinlauf & Stoller moved with me from Brooklyn, NY to Linden, NJ waiting to be used. Being tightly rolled up for 2 years made it difficult to get into a workable state for making a sloper.

I had to roll the oaktag out on the floor and keep it in place with heavy books. I then cut the oak tag into length and width suitable to each pattern piece. To stop the curling I pressed each piece of oak tag by covering them with a thick towel. Then I used a steam iron to press flat.

The ends still curled so I laid the pressed oaktag pieces on top of each other onto the floor. The I piled heavy books evenly across them.

After two days the oak tag was flat enough. The pattern pieces were laid on top and the markings transferred. I cut out the darts because I want to try pivoting the pattern pieces to change the dart intake when working on transformations.

Finished Slopers

The white slopers are for the standard Misses Size 8. The green are mine. You can immediately see where my figure differs from the standard. I have to get a hole puncher. Then the hooks from which to hang the sloper pieces.
