This isn’t a real infinity dress!
Got fooled by Butterick.
Their new B5606 looked like one of those old infinity — you can wear this dress 72 ways! — dress patterns. I just sold a vintage black knit infinity dress because it was just too big for me, and was excited to give it another try.
Alas. This is just a tank dress with long knit wings, I discovered at the store.
Serves me right for ignoring the line drawing.
