The size 6 fit perfectly for me! I'm definitely more top heavy, so having room at the top of the gown really helped. Even though I have a small torso, I felt so long and lean in it. The dress flows so beautifully when you walk as well. I fall between 5'6 & 5'7 and the size 6R worked great with 4 inch heels. I paired the gown with the Oscar de La Renta Moderne Emerald Earrings, which I got A TON of compliments on. Overall, I was very satisfied with my first RTR experience!
