Fits like a small. My daughter is 5’3” and wears most clothing in a medium, sometimes large, so she figured a L/XL would be good with room to spare. This was way too small and not very stretchy. $40 down the drain because it was final sale and we couldn’t return it. And we had to rush around last minute to find her a costume. Everything else for the costume looked to be okay.

I sized up thinking it would have no stretch as typical FN costumes don't and I wish I didn't. The dress is very ugly. Not flattering at all
