Hot Topic Sailor Moon Luna Cat Black Jumper Dress - No Size Tag - Medium? Large? Condition is Preowned. No holes or stains, however there is some loose stitches along one of the armpits, some color fade, a couple of fabric snags and some light pilling. I tried to include multiple photos to show the imperfections. Please review photos for approximate measurements and appearance All brand, size and care tags have been removed. Approximate measurements are in photos and I included a screenshot from Hot Topic website to show that it was sold there and also the website shows care instructions and fabric content
