Soybu size medium abstract-patterned adjustable active skirt

This skirt is a size medium but can also fit as a size large, due to the strings on the side making it adjustable (stretchy fabric strings in the second picture). This is a very stretchy and comfortable skirt and was a favorite of mine when I still fit in it but I outgrew it. It comes from a smoke-free home and is in great condition - no snags or other damage present.
