Love this dress. The design flatters the shape if you don't have small waistline. It runs large to me. I ordered 3X as that is the size of most items I order from FN that fit me well. 5'11 275lbs. I could have sized down to a 2X with this dress and would have been fine. Its very warm too so you wouldn't need a large coat over it or you may get too hot . I wore it on a cold winter day without a coat or sweater and I was warm.
