I used too small of a hook the first time (didn’t check my gauge!!) and it turned out too snug, but I have a smaller friend who took it off my hands (though I’ve never seen her wear it!). The second time, I used a bigger hook (a J) and it turned out just fine. I never wear it, though, because I can’t seem to get the button placed right. Crocheting wearable clothing is tough.
