I normally wear an XL (~ US 14) so I ordered an XL. It fits great open but a little snug around the stomach when buttoned as I'm heavy around the middle. I have large arms but it is not snug there. The buttons on the sleeve are a great detail. The color seems more like tomato instead of dark coral to me but it's beautiful. Seems pretty substantial and well made but I've only washed it once delicate cycle, hang dry. I bought the ivory color as well but haven't worn it yet. Plan on purchasing more colors.
