Hello all! It's been a few months since I posted - there were several unsuccessful sewing projects going on. :( But I did have one thing turn out well, a summer dress made from McCall's 4796 (1975 - it's as old as me!)
Here is my version, in cotton fabric I bought from eBay a couple of years ago.
The pattern is easy and fast to sew. The back is loose, no zipper or buttons and pulls on over the head. Everything gets cinched up with the attached belt. It's very wearable, I'm planning on making a few more at some point, maybe with contrasting fabric for the midriff and belt.
