This is a sweatshirt. It looks reddish in the photo, but the actual color is a darker salmon pink, which is very cute. The size isn't listed, but it's about the same as other size S sweatshirts, so it's roughly S-M size ☆ I think it would look great on boys too ☆ Please note that there may be some fold wrinkles. Suitable for kids size 160 Kids size 170 should also be fine.
