Pre-pregnancy I was wearing size 12 pants and typically large for tops, sometimes medium. The large is perfect and this dress is fitted. The color is very nice for any season and the pinched style makes this dress flatering for a prego woman. You may need to use a short slip underneath, plus stockings of course, but other than that, is very cute for a wedding, shower, or summer party. It's easy to put on and is a very comfortable material that doesn't feel cheap. Some cute wedges and you're all set!
