I combined New Look 6936 and vintage (well, 80s) McCall's 7572 to make the bodice that I wanted. It worked quite well, though if I make this pattern again I will make the neck hole bigger. I guess I have a big head. :P
I mostly followed the New Look instructions, but it called for elastic rather than the drawstring that I really wanted. It was simple to make a fabric "string" and run it through the casing instead - quick, easy, and I like it much better than elastic.
This may be one of my favorite machine sewing projects I've ever done. The fabric is a silky knit that hangs well, and it was very easy to make. It's not often that something turns out exactly how I wanted, but this one is exactly what I envisioned. Definitely a project I'd enjoy doing again!
