EXCLUSIVE AT NET-A-PORTER. Marysia Kids' robe is made from breathable linen and printed with charming gingham checks in contrasting shades of red, pink, blue and white. It's machine washable so can be easily cleaned after a long day at the beach. The front pockets are just the right size for little hands, while the handy hook fastening at the chest and optional belt ensure it stays shut. There's an adult version for you, too.
