If you're new to the whole idea of making bodices, let me tell you what the rest of us who have made bodices before already know: you can't (no matter what anyone tells you) buy a wedding dress pattern (or any commercially made pattern, for that matter) and use the 'bodice' section, and make what we talk about in Renaissance circles as a 'bodice'.
It just doesn't work that way, and for the following reasons:
There are two ways that I've used to get the pattern for the bodice, and both require the active and un-bashful participation of the person who's going to be wearing the bodice. You can draft the pattern, or you can make a duct tape shell. My preferred method is to draft the pattern, for a couple of reasons: when you get good at drafting patterns, it is much faster, so there's the time element. It's less physical work to draft.
Here, for the first time on this site, are the instructions for drafting a woman's sloper, and sleeve sloper. * (The men's sloper isn't in there, but the instructions are the same - just leave out anything having to do with the bust dart.) You can find the method in the book, The Costume Technician's Handbook, by Rosemary Ingham and Elizabeth Covey (I'd recommend getting the book anyway. Learning to draft patterns was the single most liberating thing I've ever done as a costumer.)
You'll need guidelines for the waist dart and bust dart, which aren't included in the PDF. There is a formula for each, and they're arbitrarily determined.
|bust size||dart size|
|waist dart = bust measurement - waist measurement|
|if the difference is:||the dart size is:|
So, for your average size 8 (27" waist, 34" bust) the bust dart would be 3/4". The waist dart would be: 34 - 27 = 7, giving you a waist dart of 3/4". If the waist is larger than the bust, or the difference is less than 4", forget the waist dart altogether.
What I will do on these few pages is fill you in on some of the things I do that knowing how to draft patterns won't tell you, and show you what to do with the sloper pattern once you have one.
* You'll need Adobe Acrobat Reader for the instructions.
