One size fits most. We suggest it will fit size 14 to 22.  Sold as a Two Piece Set but you could also wear the top with jeans or skirt and wear the pants with a different top. You will get great wear out of the pants especially. Pants have side pockets. 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 in the inside of the leg. The top is super super stretchy up top with attached peplum detailing covering the stomach area. The straps on the top tie across the shoulders for adjustability. Very chic yet comfy. Fabric is a soft silky poly blend that looks like dupioni silk.
