With a colourful monkey print, these swim shorts for baby boys are by British brand Stella McCartney Kids. Made in silky smooth recycled fibres and lined in soft mesh for comfort, they have an elasticated waistband with drawstring detailing. They have jetted front pockets, a velcro-fastening back pocket and come with a useful, sealable storage pouch. The Stella McCartney fit can be quite small so choose a size up if you want room to grow.
