Poolsiders * The JuniorsSwimming and playing in the pool is amazing. But you can have loads of fun at the poolside too! Swap your wet swim shorts for The Poolsiders and play beach ball or have a scoop of your favourite ice cream. MR MARVIS' royal blue stretch cotton junior shorts go very well with a white or with no shirt. Go from belly flops to flip flops, and update to slip ons for the evening. Because young misters know: style has no age.
