Unfortunately, this retro pattern (Butterick: B5033) is no longer available.
But since I would have had to adapt it to my body anyway, I’m trying to recreate it using my own basic bodice. However – as you can already see – I’m going to rework the back to make it a halterneck. This is my first attempt but I think it goes into the right direction. The collar is still missing though!
