Over a decade ago, I happened upon an amazing selection of vintage sewing patterns in a thrift store. Most of them were immediately put on eBay, but I did keep and make several.
My favorite was Simplicity 3263, from 1950. It was a simple shell shirt pattern, with some interesting double dart details. The original owner (Betty Rose--she had written her name and address on most of the pattern envelopes, and I was actually able to look her up and learn a bit about her) had extended the sides of the pattern, and I cut it that way the first time I tried making it, and I liked the way it fit. I made the shirt a few times, every one extremely cute.
Eventually, though, I gained enough weight that the vintage size 14--even with the modifications--was just too small, so I sold that pattern, too. Years later, I developed a sudden nostalgia for it--I considered trying to recreate it by hacking some other patterns (I am not up to making a personalized block), but I couldn't get a result that I even wanted to test. I looked at what options were for sale, and even managed to find Betty Rose's old pattern for sale on Etsy.
I let the interest fade, but it jumped back recently, and I found a vintage size 18 (B36) version of it on eBay--for more than I usually spend on a pattern, but not bad for a vintage pattern, so I got it. That was also around the time I got the die cutter, so I was distracted by that for a while. But! I finally tried making the size 18!
It's a little large! But I can work with it!
