Reposhing this item I purchased from @gawdyvisions. Loved it, but the person wearing it decided good over evil....and Glinda the Good Witch won out! Notes from trying it on after receiving it: The package indicates that the costume is an adult costume, one size. It does not specify measurements; however, I would say it would be a good fit for an adult M/L. The dress has ties for the back if to tighten the top if need be. Questions? Leave a comment below!
