THIS IS A ONE SIZE FITS ALL, I am a 10/12 5'6 and it fits a little snug.  but thats okay.  The quality is not the greatest.  The sequins seem a bit loose.  It also shifts when you walk because the lining is not sewn down very well.  with all that said, it nice for a few wears. I would recommend as long as you know that its sub par quality coming from China.  It arrive in about 2 weeks.
