I am 5'8, 126 pounds, 32DDD bust, w/ a rectangle figure, some fat evenly spread through my body, I usually get a Medium. This dress was not suited for my rectangular shape--the hip part is way too wide (so wide that it's not fitted to my hips, just open loose space). I'm not skinny, I have 'moderate' hips, and it still was too loose. Also, the chains look a little cheap. Might work for someone who has larger, curvier hips.

Tried it on and it fits nicely. So simple but sexy
