This is a pajama shirt with panda print in good used condition. The material is not cotton, it is 97% polyester. If not sure about size, please ask for measurements especially if you are not familiar with how this brand fits. People come in all shapes and sizes and the number/size on the tag doesn’t always mean the same thing across brands. Poshmark does not allow returns due to size, or item not fitting. It is up to the buyer to ask questions and know they are buying the right size. I put up as much information as I have on the item and always put up the listed size. I am happy to measure item upon request.
