I was so in love with this dress (and because I couldn't find it anywhere else!) I purchased a size 6. I am a size 0, so it has been taken in. It has no signs of alterations, other than the build-in traditional bustle with 3 loops and 3 buttons in the back. The back is corset and very easy to adjust. I am 5'3, 105lbs, size 34C bra. This dress could easily be adjusted tighter or looser if needed, or cups sewn in the bust.
