After reading other reviews, I anticipated that this dress would run large. In my opinion, it runs true to size, if not a bit small. I usually wear a size 8, and just found I am pregnant. The size 3 fit perfectly. The draping was also perfect for concealing my little "bump" and I could have a full dinner and not feel constricted by the dress! It was sexy without being vulgar. I wore it for a night out in Vegas, and felt great in it! The only thing I didn't love was the bra I had to wear with it--one of those sticky cup kinds. But I felt the way the bodice was built a bra may not have been necessary. I really liked it!
