Patterned in a yellow starfish print, these green swim shorts for teen boys and girls are by Stella McCartney Kids. Made from recycled material with UPF50+, the fabric is silky smooth and lightweight. They have an elasticated waist with a faux drawstring tie on the front, and useful side seam pockets. The Stella McCartney fit can be quite small so choose a size up if you want room to grow.
