I bought this dress for my college graduation, and it's truly gorgeous! i love the loose, breezy fit, but it did feel just a little bit sack-like on me, definitely more-so than i expected from looking at the product picture, even after sizing down to a small (which was comfortable, and i'm usually a medium). i ended up pairing it with a small belt. 

really pretty dress, just be advised - leaves a *lot* of room around the waist!
