I rented this for a summer evening black tie event and it was perfect. It does run small however, especially the midriff section (side zipper). I usually wear a size 6 (5'6", 140 lbs.) but could not zip and had to go with the 8. The fashion tape that was included is helpful around armholes and for very low V neck so bra is not visible. A racer-back bra is ideal for this dress.
