Copy your Figure: A Dressform Tutorial part 1

This post is a follow up to my January post about various commercial dress forms and DIY methods sewists use to try to get a decent dress form. Though it's been a while, I didn't forget my promise to write a tutorial to make THE BEST mannequin that really does duplicate your figure. In my defense, I just finished mine in September, (though I admit I've been using it anyway, pins and all) so thank you for your patience. To keep this tutorial from growing into an unmanageable mess, I'm going to break it down into smaller parts.


The key to success is in the accurate making and fitting of a french lining or Moulage, which is a sloper, master pattern, or fitting shell  that has all of the wearing ease removed. Because this lining will become the cover of your mannequin, from here on out, I'm going to just call it a cover. 

Supplies you will need:



~ A fitting shell pattern of your choice
~ Quality 100% cotton muslin yardage- the best you can afford. DO NOT PRESHRINK! 2 yards will be plenty.
~ A sturdy mannequin- smaller than your own figure measurements
~ measuring tape
~ clean spray bottle
~ 100% cotton batting
~ various rulers both curved and grid- C-thru
~ soutache braid
~ thread
~ pencil
~ scissors
~ disappearing fabric marker
~ dressmakers carbon- I prefer the waxed type
~ tracing wheel
~ dressmakers pins
~ hand sewing needles
~ sewing machine
~ Paper for copying your pattern- Use tracing paper on a roll, usually 12-24" wide found in the art section of your craft store(If you need wider paper, tape two sections together with transparent tape). While you could skip over the copying of your pattern, remember that a final pattern of your cover will come in handy if you ever need to make a new cover for your mannequin without going through the fitting process again.

Step One: Prepare the Pattern

1. Start with a Master Pattern that you like
The only pattern pieces you will be needing are the bodice and the skirt, both front and back. Be aware that I am not endorsing ANY of these patterns. I list them only as possible sources.

.
2. From Bodice with darts to Bodice with princess seams: FRONT.
If you are using a princess seam pattern then skip this section on dart mannipulation. It's also important to mention that you should ALWAYS use a ruler to trace. If you do this freehand, your work will not be so accurate.

If your pattern does not have a seam line marked, use a ruler to mark this line on your pattern. Carefully trace off your pattern pieces, tracing only along the seam line.  This is the important line to know, and at this point, we don't care where the cut line is. If your bodice has two darts, manipulate the side dart to the shoulder to make it a princess seam.

Here is a good video on You Tube that shows how to do that:
http://www.youtube.com/watch?v=pwTv7bBN7XE .

Use a ruler to connect the two darts from the shoulder to the waist. My pattern has only one dart at the waist, so I used a curved ruler to mark an attractive princess line to the shoulder.

Now we need to actually divide the bodice into two pieces by tracing off the two sides:  Start at the neckline, down the center front, squaring off at the waist, up the inside leg of the waist dart to the shoulder, across the shoulder and neck to the center front.  Add a grain line parallel to center front, label your pattern and add a notch or two if you desire. Do the same to the side front, carefully tracing around the outside leg (farthest from center front) of the darts, shoulder, waist and side seam. Add notches (if any) in identical locations to match up with front pattern, grain line parallel to center front and label. Now add a 1" seam allowance around both pattern pieces, transferring the notches to the cut line.

3. From Bodice with darts to Bodice with princess seams: BACK
On the back bodice, draw a slightly curved line from the shoulder dart to the waist dart. This line will be come your princess seam line. Copy off the Center Back and Side Back pattern pieces the same as the front, adding a grain line parallel to the center back, labeling, notches if desired, and 1" seam allowances.

4. Give your skirt pattern princess seams too!
Measuring from the waistline down center front and back, perpendicular to the grain line, shorten the skirt pieces to about 16-17". Be sure to "walk" the pattern side seams to make sure the front and back are shortened the same amount.

Draw a line from the inside dart tip to the hem. Make this line perpendicular to the center front and back. This is your princess seam sewing line. If your pattern has a second dart, you can leave it as is, allowing one more fitting element, or combine it by transfering that dart space to the dart closest to the center front. Trace off your skirt pattern pieces as before, adding  a 1" seam allowance and  labeling them skirt front, skirt side front, skirt back, and skirt side back.

Step Two: Layout , Cut, and Sew

1. Layout
Lay out your pattern as you normally would with the pattern grain line parallel to the selvage. Cut 2 of each pattern piece.  I pin on the inside of my seam line rather than on the edges, and because I want my seams to be ultra-accurate, I use dressmakers carbon and a tracing wheel to mark the seam line.





2. Pin along seam lines. Sew it up with a basting stitch. Press lightly or not at all. 
Carefully match the seam lines using a pin in the mark on both front and back to hold the seam together. 














The sewing order:

First, sew the bodice and skirt together matching bodice front to skirt front, bodice side front to skirt side front and so forth, sewing at the waistline.

Second, sew the princess seams, matching fronts to side fronts and backs to side backs, matching any notches and waist seams.


Third, sew shoulders and center front. I left my side seams open because that is where the much of the fitting adjustments will be needed, and the back so that the model can get it on.


Here is my pre-padding mannequin wearing the cover I just made with the side seams pinned together. The cover still has the wearing ease, but you can see that the mannequin is smaller, especially in the hip area. The princess lines are also in the right location, centering over the shoulder and bust points.

Making the Case for a Dress Form

I am not automatically a proponent for sewing gadgets. First, it has to prove its usefulness to me. Gadgets and tools cannot take the place of technique - like a good screw driver, it can make the job easier, but will never replace the need for practice and knowledge. The more expensive the tool, the more need for establishing its worthiness to my life and budget.

In making the case for a dress form, the best ones will cost hundreds to thousands of dollars, and the personal dress forms are a whole lot of trouble to make, so it's a decision that can't be made lightly.
I've draped a new design idea. Looks great!
First ask yourself, what will I use it for? Why do I want it? I use my dress form now in ways that I never needed before college. I use it to test a new design idea. Like at the fabric store, I drape my mannequin with a quick drape to see how the fabric and style idea will go together.

I had to drape the sash on this design I call Espire.
I use my mannequin during the pattern making stage to check things like the flare of the skirt, the gathering of a drape, or the depth of a neckline.

While I sew the new style together, I keep the garment and cut pieces pinned to the mannequin so that it's ever present in my mind and in my view. It's the designer "instinct" that can flag my conscience if something isn't working as expected. In this way I have a another chance to nix or improve a bad idea during this stage of the development.

If the style demands it, I need to use a mannequin to drape the pattern for part or portions of a new design style, as in the hip drape on this red dress I call Espire.



I consider a mannequin invaluable. I own two: one is a Styrofoam in size 6, and the other is my base size 10 in paper maché from dress rite. I use them both equally. But for all the things I do use them for, what you might notice is that I don't use a mannequin for fit. Why not? Because a dress form represents the body of everyone, yet no one. To check fit, I use a real person, a fit model. I talk about that in one of my earlier posts. To use a mannequin for fit, it would have to be a near perfect representation a real body, and even if it did match the measurements and body type I needed, it would still have limitations.

Many manufacturers have tried to produce mannequins that dress makers can use to help with fit. Probably one of the most common is the dial form. You are able to adjust the sides, bust, and back as necessary using the dials. I've never tried to use one of these, but it looks like guess work, and seems like it would be hard to duplicate bodies with a rounded shoulders, large abdomen, or a swayed back.
Another type of adjustable form is like the small Styrofoam form I have. It came with pads and a cover to keep the pads in place. No matter how I tried, I could not pad the form to match a real body, or lengthen the back waist enough. The shoulders are incredibly wide too. No chance of making those smaller.
Using paper tape
For Do-It-Yourselfers, it's popular these days to make a copy of your body by wrapping yourself very carefully in paper mailing tape or duct tape. The idea is that you wear a long t-shirt, knit dress, or garbage bag and have a buddy tape you up with a few layers from neck to hip. There are numerous posts from people who have tried this, so getting the directions isn't a problem using google. What is a problem is that the end result isn't very accurate, it's unpinnable, and they actually add inches to your figure that aren't there! I have tried both of these methods and was not very satisfied with either.

A more accurate method for do-it-yourselfers is to wrap yourself in a plaster cast (like a medical cast for a broken arm) and then fill the cured form with spray foam. Remove the cast, and voila! You have an actual body duplicate that will take a pin and can be marked with waist and seamlines. There are instructions on the internet from a company that sells kits and will do this for you if you want. Check out My Twin Dressform if you are interested. (NOTE: Even though I make this method sound really easy- it's not. Plaster hardens very fast, requires special cutting tools to remove, and can be dangerous to children who might want to play in it. When so encased in plaster, fainting is a real possibility. Please, do not take lightly using this method for making a dress form!)

Saving the best method for last, a very safe, and very accurate method to get yourself a body double is to sew yourself a princess seam moulage or french lining which is a fitted sloper or master pattern with no ease. Pad any suitable mannequin (smaller than your actual measurements) that you may have to fit the moulage. This method requires no long calculations, only a helper. I'm going to do this with my fit model next week, and will leave you with photos and instructions hereafter. Stay tuned!
