I am size 2, this dress is size 4. I was feeling like a princess. No tears, no stains, no one will notice you are wearing a used dress. You will need to replace one button, and one button loop on the back (I used them for a bustle).
My stats: Chest 34, waist 27, hip 36. The dress can fit a larger chest, but larger hip would be too snug. My height 5"4, weight 117, shoes I wore to the wedding - 3 inches.
