This is a size 6 Casablanca 2169 lace dress with 3/4 sleeves. I had it taken in slightly and hemmed as I am 5'4 and I was originally tripping in it, it also has a bustle. I also had bra cups sewn into it because the back doesn't allow for wearing a bra.
I bought a Navy sash online which I am happy to include as well.
It was very comfortable and I enjoyed having sleeves. The back has faux buttons but is actually a zipper which made getting it on very easy!
