Thank you for visiting! m(_ _)m This is a set of a HAKKA BABY sweatshirt and navy pants. The sweatshirt is made of French terry, and the pants are fleece-lined. I received this as a gift and wore it a few times, but I think it can still be worn. However, as shown in the 7th photo, there is a small hole in the knee. Please consider this before purchasing. Thank you.
