I wear a large in tops but order an XL in dresses and bottoms because I want the bottom to fit, so I did that here-- no regrets! The skirt fits perfectly and the material has a little bit of give and really smooths everything out. I'm a 36C or D and the top is a little loose around the chest in XL but no big deal. I can not WAIT to wear this in Vegas for my bachelorette!!
