All items are brand new and purchased from Belle Maison. My child outgrew them without wearing them. How about the quilted underwear for the coming season and the short-sleeved T-shirts for next year? *The quilted underwear doesn't have batting sandwiched inside; it seems to be two layers of thin fabric pressed together with a grid pattern (I apologize if I'm mistaken). The main body is 100% cotton. My child wore the T-shirts with different patterns, and I thought they were slim-fitting overall, so they might fit children who wear sizes 100-110. They are brand new, only taken out of the bag for photos, but have been stored at home. Because of the thickness, I will pack everything together in a bag.
