Size medium, 2-piece, striped button-up dress with detachable zip-up corset to go over top. Can be worn how the model wore it or how I wore it with the corset reversed. ***For reference, I am wearing a size small in the photos*** this item for sale is a medium and completely new & never worn before! Still has the tags & original bag it came in! Such an amazing & flattering fit with quality & stretchy material.
