This is a knit fabric outfit. It seems easy to move in because it's stretchy. The pants are made to be loose-fitting. Made of 100% cotton, I used it thinking it would absorb sweat and be gentle on the skin. Although there is some wear and tear, it's a material that doesn't easily lose its shape, so I think it can still be used for a long time. There is some pilling. I've worn it for one season as loungewear. It was so cute with the ears sticking out from the outfit. It's a set, but it's also cute to wear the pieces separately. The size is indicated as 70, but please check the detailed measurements in the photos. Please consider this item with the understanding that it has been inspected by a non-professional, stored at home, worn by an infant, and is secondhand.
