i think your best bet is to be comfortable but also check and see if the club is having a theme the night you are attending, do they have attire rules (no jeans for instance), do they provide towels, lockers.
for ladies i say be comfortable and sexy and bring a robe if you don't want to walk around in a towel or naked or a nice piece one piece dress you can pull on.
My understanding is that you need to mix it with the right amount of warm water, to get that great slippery consistency.
It performs really well if you mix it in a bowl together rather than trying to apply it to your partner then add water.
I order it here: - just enter NURU in the search bar.
