Well it just doesn't work that way, does it?
Anyway, my friend was making costumes for a community theatre group and had to make a frock coat for a gentleman with a 58 inch chest and a 64 inch waist. Yes, a challenging figure to draft and fit for. So, he picked up his trusty photocopy of the MTOC, (that he hadn't used in years) and started to draft a body coat for this gent, plugging in his numbers and diligently following the instructions. Then he got to the point of knowing that it didn't look right and he called for help.
After dinner, over to my house he came with his draft, and his book and his frustration with it all.
What can you do in a situation like this?
So we sat down, and I tried to help him, without referring back to the original draft, because I knew it was trouble. Did he have a full set of measurements, no. Balance measures, no. Photos, no. OK, so we are just winging it here, so I started drawing on his paper correcting where I thought it was wrong, and offering encouragement where I could, without completely overwhelming him with information.
The point to all this rambling is that I wished I could help him visualize the shape of the person and relate it to the pattern lines on the paper. This is where photos are so helpful because they can indicate things that you may miss in person, or at least sometimes give you a bit more of an objective viewpoint- a bit of distance in a way.
The numbers are just numbers and they don't always indicate where the shape is. One of the most difficult shapes being the very large- because people don't gain weight in a proportional manner.
The drafts for these sizes often apply the extra sizing in one area- the centre front.
As you can see by my drawings, in profile, adding to the CF looks like it would work, but when you see the shape straight on, you realize that the body is more complex. In this case, the pattern needs manipulation at the sides as well. In reality there are many pattern manipulations that could be done for this body shape, I am just simplifying to make a point. I will point out again and again, that it is so much easier, to have fabric to pin away rather than have to rip open and repin or guess how much more is needed. I don't advocate making a huge shapeless garment but don't be too skimpy either.
Is there a one size fits all solution? No, sorry. Since each body is different, I do think that visualizing the body shape in three dimensions helps to understand how the fabric will go over it. I guess it is more like sculpture in a way. If you can see the shapes in your minds eye or drawn out on paper, you may have a better chance of success when applying the numbers, or feel freer in deviating from the formula, when things are not working.
In other news, I am making progress on my instructional booklet project, I think I have much better quality now in the photos and like any teaching project, I too have learned a few things along the way!
