Second, I don't appreciate instructions to clip to reinforced corners before stitching (as in the yoke attachment). It's lazy pattern making. Indie patterns don't do this. They expect better techniques from their users (or teach them in the instructions).
The pattern didn't call for topstitching, but it's a go-to detail for me. And I used it to hold a lot of facings in place, including all along the back. (Now if only I had remembered to interface that neckline facing. Oops.)
