I wore this dress to my bosses wedding, and let's just say i got promoted a month after. haha I am usually a size 6 . This dress does wonders! I ordered the Small and the Medium. i could have worn the small, but I chose to wear the medium because the small was very scandelous on the top (husband wasn't too happy). i loved it and definitely will wear an Herve again. it's very slimming. I felt like a million dollars... I really didn't want to give the dress back. Totally had seperation anxiety.
