any type of swim wear is allowed..no nude bathing allowed
I know that nudity is not allowed at the pool. speedo or burqua. :-)
I don’t think so. You’re asked to wear a decent swimsuit to use the pool.
I’ve seen g-strings being worn at the pool. So I guess so. Most tend to just wear the towel & nothing underneath. But you need swimwear if you want to use the pool.
