The admission rules say the following:
"Guests with tattoos or fashion tattoos (body paint) are strictly refused entry.
Also, please refrain from overly revealing swimsuits.
(If staff notice after entry, you will be asked to leave.)
3. Swimming in anything other than swimwear (including rash guards) is not permitted."
So I guess it's fine as long as nobody sees it, but you definitely have to wear a rash guard?
