NWOT MaxStudio Skirt!

I just purchased this and I regret it because its too big on me. Already took tags off so too late to return. The skirt is a XS but I’m listing as a Medium because it is definitely fitting like that and also could fit a Large because the waistband is so stretchy. Waist is 13in and it’s about 20in long hitting right above the knee! Gorgeous material and color.
