I rented this dress for New Years Eve and I absolutely loved it! I got so many compliments. I was deciding between a 2 and a 4 and I ended up wearing the 2. They fit similarly in the body (both stretchy so i could have worn either) but the sequined back part ran a little large. Even the size 2 had a little extra "space" up around the neck area, but wasn't too noticeable. The dress does run longer than it looks on the model. The rouching in the dress made it look wonderful! My only complaint about this dress is that the sequins did rub against my underarms throughout the night, and I was sore the next day from irritation. Other than that, I loved this dress! Definitely recommend it for a classy, formal night!
