PZ, like I said.....a good towel dry and clothes that go over bathers!!!
What if you're like me though? Swim in winter, and don't have a car. So we'll be going home on PT. Eh, I reckon a big towel around and then another to dry with and get dressed under with by the side of the pool will have to do for a lot of situations in my future swimming expeditions with children. DD is easy now because she's so small
