One size truly fits most. Sold as a Two Piece Set but you could also wear the top as a dress alone and wear the pants with a different top. Side high low hemline with crystal buttons down the front. Side pockets. Sleeves are puffy with pleating detailing. Pants are oversized wide leg with attached sash tie belt. We are showing with the sash belt tucked inside the waistband allowing the sash to hang down the inside of the leg. Elevate your wardrobe with this beautiful outfit. Very chic yet comfy. Fabric is a soft silky poly blend that looks like dupioni silk.
