This is the Sezane Diana dress in Garnet. Still have the tags on it. The size is technically XL, but honestly I think this works best for a size 6 (comfortably) or 8 (with shapewear underneath). It is a little loose on top and fitted on the bottom. This is one of those dresses that doesn't have much hanger appeal, but once you put it on it looks very flirty/pretty.
