Buy something much larger than you'd normally wear. I'm a size 10 and bought an XL, but an XXL might have been better. The laces in the back help a lot, but I had to leave a 3-inch gap so it would fit. These likely are made to fit a tiny Asian woman, so think accordingly. Otherwise, it was a big hit at the costume party. Paired with fishnet stockings, this looked great. By the way, I added ribbon ties to the bodice and tied them behind my neck. I wanted to be sure the top stayed in place. You might do the same.
