Type... Pajamas Sleeve Length... Long sleeve Design... Animals White is size 70. Green is size 80. Made of 100% cotton, so it's soft and I don't think it will pill. I used it for one season because it's good for preventing the stomach from showing. I used it in rotation with two other sets, so I don't feel much wear and tear on the fabric, but there is some feeling of use. It's very cute when worn, so I hope you'll use it (*^^*)
