I tried this dress on in the store but decided to think about it because of price. i ended up buying it later on line. i usually wear a medium (5' 7" 128 lbs wide shoulders) but got a small in this dress. it does run the risk of looking like a sack but sizing down did the trick! the easy going loosness yet elegance is why i like it. it is so comfy but looks lucious. i plan to wear it often this fall and christmas.
