This item is only the left one. There's no size label, but it's about the same as a size 70, so I'm listing it as a 70. 100% cotton. The mesh is only in the middle. The left side has some stains around the neck. The whale in the middle has no particular issues. The car on the right side has stains around the waist. All items show signs of use. The right side opens in the front, which was convenient for checkups and injections. I'm selling these because my child has outgrown them. Please understand that there may be some folding wrinkles. Please only purchase if you don't mind. Please check my profile. Thank you very much.
