Mini-me blue swim shorts for boys by luxury French brand Vilebrequin, made from a smooth recycled fabric. Adding fun to this poolside style, these shorts are water-reactive, magically revealing a tonal Piranha fish design once immersed. They are quick-drying, and have a comfortable elasticated trim, with an adjustable waistband for the best fit. There is a soft and seamless mesh lining, and side seam pockets. To complete the look, a tonal fish motif is embroidered on the front, with a distinctive logo patch on the back.
