I inherited a huge stash of vintage sewing patterns and fabrics a couple of years ago when a friend's grandmother passed away. She made all of her own clothes and obviously had excellent taste! My favorites are the 60's era McCall's, they look like something Joan would wear to the office on Mad Men. Especially this...

The problem is that all of these super fabulous patterns I'm dying to make are a much larger size than I am. Most of these fit a 39-41 inch bust and I am a scant 31 1/2. I've made a few dresses from simple modern patterns (with lots of mistakes and trial and error...but I'm getting there). Should I bother trying to grade this pattern down or will it just make me want to stab myself in the ear with dressmaker's shears? I've also thought about trying to find some sort of vintage pattern swap so any suggestions there would be great.
