There is some pilling, but I think it can still be worn. It's warm because it's corduroy! The character on the side is also cute, and I used to dress my child in it when we went to Disneyland! It really stands out! My child moves around a lot, so it was helpful when trying to find them (^◇^;) If you're looking for one, please! I have a lot of children's clothes for sale. I will discount the shipping cost if you buy multiple items! Thank you.
