It fit perfectly! I also rented the 8 just to be sure but the 6 was the perfect fit. It was a very elegant dress. Everyone complimented me at the prom. I wore high heels but I had to temporarily hem it because it was too long (but I'm used to shortening clothing!). It was also extremely comfortable. The top would stay up, so I did not have to keep pulling it up. I would highly recommend for any formal event!
