Hot tub date night with another couple?

This weekend my boyfriend and I are going to double date with a friend of mine and her boyfriend. We are going out for dinner then coming over to chill in the hot tub for a few hours.

We haven't talked about what anyone plans to wear. Should it be brought up? My boyfriend is usually naked and I'm either topless or naked. I don't know what our friends wear or plan to so I think it should maybe be talked about?

What should i do I do or have anyone else had this experience?
