I jumped on the bandwagon and made the McCall's dress. It is usually warm here until November so this should carry me through the next few months.
I used a thrifted sheet from 1976 for the main body and newly purchased fabric for the contrast. I'm not thrilled with some things about the dress, and if I'd looked at all the pattern pieces before I started sewing I might have changed a few things. I don't like how the contrast band doesn't go around the back of the neck, I think the sleeve length is a little weird and would be better with a smaller width of contrast. I would extend the front gathers to the side panels for a little more fullness. I need to add a snap to fix the tie to the back cause it keeps slipping down, or I might just add a little strip of elastic in the back.
