I bought this before! I haven't worn it many times, but there's some pilling on the elbows and knees. It's not very noticeable (see photo 3). Overall, I think it's in good condition, so you can still wear it! It's not thick, so it's perfect for this time of year! It's a striped pattern, so it can be worn by girls or boys! It's a set of two, beige and navy. I have another set because they're twins! If you want to buy a total of 2 sets, please comment. Size is 70.
