I ordered two sizes, and true to the below reviews, needed to wear the smaller size. However, I realized that the larger size had a slip attached inside (keeping it from being see through) and the smaller size was missing this part of the dress...so before my event I had to spend my afternoon finding a black slip to wear underneath instead of getting a pedicure :-( I like RTR, but they should double check to make sure that the dresses are not missing critical parts!
