I'm 5'1 and 155lbs. 36" bust,  34" waist, 42" hips. (Pear shape) I typically wear a size 10-12 in dresses = size medium/large. Ordered an XL. The slit on the side went to my upper thigh/hip, would ride up as the fit around my hips was super tight. It is also very see through. Definitely Asian sized.
This is more of a club dress than a professional or casual if you're able to be comfortable in it's conditions.
