H&M Denim Knee Skirt

H&M Light Denim Skirt. 5-pocket, knee-length skirt in washed denim with distressed details. Zip-up fly and raw-edge hem. I bought this skirt in-store, and the tag said it was size 10. The managers mentioned this was maybe a mislabeled skirt because it fits like a size 2. It was not a kids skirt due to the denim label. The tag says size 10 but fits like an H&M size 2.
