I rented this dress for a formal affair and it was a big success. The photographer at the party came up to me just to photograph the detail of the dress. My husband also couldn't be happier! I ordered size S only because M was rented out and was surprised to find out that it fit perfectly. The dress does indeed run large. M would've been way too big on me. I didn't have any problems with the straps at all that other reviewers described. Perhaps, because I'm tall and my shoulders are decently sized. The straps stayed perfectly well in place all night. The dress is very comfortable to wear. I wore a strapless bra underneath and put some fashion tape on the sides just in case. I didn't have to worry at all about the dress riding up or down. When I ordered it I was concerned that it would be scandalously sexy / too short, but the dress looked very classy. Even on my 5'11'' frame the length was just right. Rent this dress and you won't regret it!
