New Look 6871. It looks like maternity wear. You can't tell from the envelope but the back is just as gathered as the front. The armholes in front gape, due to the yoke and body connecting at the wrong angle. I may reduce the gathers or turn them into inverted pleats and try again. I forgot to take photos and it's half disassembled now. Oops.
I'm disappointed because this took half my afternoon. I so wanted to make a cute top, or just something!, but doing anything is hard when I'm in so much pain.
