I'm typically about a size 8 and I wore the size 8. I can sometimes pull off a 6 and other times I do a 10. Bust is about 39, Waist is 29 and Hips are 40.5.. I also took the 10 as the additional size, but the 8 was perfect. I felt secure in it all night and had lots of compliments. I was too busy to take pictures at my event, but my man took this of me at his place afterwards.
