I rented this dress for my husbands military ball and being pregnant I ordered a size larger than what it usually wear. I soooooo didn't need to, it was a little bigger so it allowed a lot of moving and dancing room. Loved this dress, unbelievably comfortable and gorgeous on to boot!!!! I am also 5'6 and wearing a two inch heel it was the perfect length. Would definitely rent again and refer it for someone else!!
