I bought a small based on reviews. I am 165 lb 36DD and usually wear a medium. The waist down fits great but the cups are super weird not for big chested girlies. And the material is very thin you can see right thru it. Will probably give this to a family member or return it ):

this is a fantastic dress!!! only thing I didn’t like is that that the material with the glitter is rough. listen though, no bra needed! It pushes up your girls nicely and it’s very stretchy, youwill break necks in this mini dress!!!
