The costume is absolutely a perfect fit. The material is very stretchy and comfortable allowing the fabric to hold and hug all the right places! Be careful though, it is white and will pick up and and everything to touch of bump into. Also if you aren't very confident in your bust area this might not be a goo choice for you because it is a low cut halter top dress so most of your cleavage is out. With the right accessories it's a great buy!
