TOLANI Collection - Floral Ruffle Maxi Skirt, Medium (?)

Gorgeous skirt with a flounced ruffle overlay that moves when you walk. Easy pull-on style with elastic waist. In perfect condition. 100% Polyester, Made in India. This is equal to a size Medium, but the tag says 'XS', which I believe is an error. See measurements: Waist 30" (unstretched) , Length 41".
