I'm 150lbs, 5'8", & ordered a large. The dress looked like the picture, (blue with white stars) only miniature. It fit in the sholders & sleeves, but it was as long as a shirt.  It fit in the waist & chest, but the skirt.. omg,  it didn't come close to covering anthing.. it looked a Ginger Spice dress.. if u don't know what that means, just Google it.
**update** after returning the dress, I was issued my refund promptly, however the seller has contacted me numerous times complain that my review was influencing a lot of people negatively, and asking if they could "make it right so I change my review". I was already issued my refund, so I don't know what more they want from me. The emails every few days is really annoying tho.
ANOTHER UPDATE***
The seller has now sent me 7-8 emails, but I have told them I WAS ALREADY REFUNDED!!! Idk what is wrong with these ppl, but they are insistent on me changing my review of this crappy dress.
