I agree the old bikini-only rules were problematic. The sport has been moving away from that - FIVB now allows one-pieces, tank tops, and shorts for women.

On MyNextCamp, I show whatever dress code info the organizer publishes (if any). If you see outdated or concerning requirements, that's worth flagging to the organizer directly - or choosing a different camp.

I am adding more as I find them and try to validate them by reaching out, still early days though.
