I just bought a pattern, number 3943 from Butterick's See & Sew line (not because I wanted something insanely simple, but because it was the right garment). I made the top, which is a pullover tunic kind of thing in a lightweight knit with bust darts and a little bit of shaping.
Partly because I didn't measure the pattern pieces carefully enough and partly because I didn't mentally understand what 5 inches (for example) of ease would mean on my body in this style of shirt, I made it up and it came out size Tent. I have narrow shoulders, a fitting problem I am aware of, but it wasn't only too big in the shoulders- it was much too big through the waist and hips too. (Ironically, the sleeves are perfect, lucky me.)
I cursed, of course, then played with it for a while and wound up taking a tuck in the center front and back that varies smoothly from 1 7/8" at the neck to 1 1/4" at the hem (that's the depth of fold, if that makes sense to you- that's the amount removed from each *quarter* of the pattern. I told you it was enormously too big!) Basting along that line and trying on the top after indicated that I could save this one simply by putting a seam there; it looks intentional. The issue comes when transferring my changes back to the pattern.
It is a multisize pattern, but the sizes are sold in blocks of three- so this one is 20-22-24. Given how much I've lopped off, I need a size several much smaller than 20 (otherwise I'd just measure the pieces I wound up with and choose the size of pattern piece that matched most closely and alter from there).
So since I don't want to go buy another pattern (I cannot get to a Joanne's for a 99 cent sale, that suggestion won't help me) my question is: can I just lop off my almost 2" from the centerline of each pattern piece and then smooth the neckline? Or is there a more correct way to handle this?
(More irony: if I had measured the pieces correctly I'd still have a problem, because it would have proved to me that nothing in that pattern envelope was actually my size... grrr. I wonder if it's something with the ultra-cheap billed-as-ultra-easy See&Sew line; the skirt I did for a friend with another Butterick pattern did not have this problem.)
Thank you, Courtney
