This Union Made figure flattering dress is super stretchy and includes the original matching sash / belt. Brand is Lady Carol Of New York. Tag says material is 100% Double Knit polyester meaning the fabric is thicker and has a bit of weight to it. Colors are yellow with black accents. The buttons are black and round. Some look like they are starting to loosen so you might want to get them tightened at some point.
