I cut a size 20, which turned out perfect. The pattern goes up to a size 34, which is a 61.5 inch bust and 65 inch hip.
The instructions tell you to "burrito" both the front and back yokes, but I ran into some issues on the back yoke burrito- not quite grasping that it was going to be a tight squeeze with the keyhole (it would have helped if I had reviewed the instructions or the sewalong on the Sew House Seven website).
While I was able to sew it up just fine, pulling the fabric out of the burrito was dicey and I ended up accidentally ripping the bottom of my keyhole. I was able to salvage it with some Wonder Tape, tweezers, and topstitching around the keyhole, with a dab of Fray Check to be safe. I went ahead and topstitched the yoke seams, too, while I was at it.
I took a narrower hem because I didn't want to lose length. Maybe 3/4 inch as opposed to almost 2 inches? It's perfect with high-waisted jeans.
I love it! It has a modern-but-vintagey feel, the fabric is very cheerful, and it fits really well.
