I purchased this dress for my daughter to wear to her senior prom. To figure out what size to order, she wears a size 8 in pants and a 9/10 in dresses, I read through the reviews. The reviews mentioned that the dress has stretch in the fabric so we went with the Medium, which worked out great! She is 5'7" and wore a short heeled shoe. We didn't have the problem with the dress being too long like some of the other reviews stated. It was actually a perfect length for her. The quality of the dress was good too. It is not cheaply made and worth the price!! I highly recommend this dress for whatever function you are going to.
