Bought for myself Last week off of mercari please go by the size chart in the photos because I didn't & it didn't fit me :( it's a super cute outfit, it's brand new but to me had a light sent so it will need washed ( in my opinion) I just want my $ back on it. thank you. it's a grey & white matching 2 piece xxl set Ken max brand outfit. also it doesn't have tag's it came in Manufacturers packaging with a sticker. just want to let you know that as well. thank you!
