Adidas Sweat Skirt

In good used condition! Piling on the inside! Purchased from the thrift store & Size Tag had been cut off! Side tag says 12/14 but I’m unsure if that is the size! I purchased it tagged as a size S but I wear sizes m/l & it fits perfect as a high waisted skirt! Some thread is coming undone in two places & shown in photos! Ruler in photos are used as a reference for waist & length! 💕
