Dolfin Viper Youth All-Over Racer Swimsuit Brief

My son has made the red white and blue Viper brief as his racing brief and while diving. The fabric is lightweight and has faded a bit from chlorine in the past 9 months he's been wearing them. He likes the Olympic-style bikini cut, which his idol divers wear. Only drawback is they started getting tight just recently while his other suits still fit. They've started irritating the skin on his hips at the side seam. I think he probably will decide on the same color/pattern in the 26 because of the slim sides, when we place our next order.
