Mine has always worn wetsuits which seem to work well (practical, no flapping about) but he has now announced they are "babyish" and he wants separate top and shorts. I think in theory what he needs is trunks + rash vest, but everywhere I look is either enormous flappy board shorts, long skintight leggings, or really tiny Speedo type things, usually with no matching top - the first isn't practical for lessons, and he doesn't want leggings or Speedos. If anyone's DS wears the kid of thing mine is demanding, could you post a link to it to help a frazzled mum out?! TIA!
