Depends what night you're attending
Chams is Friday only, greenhouse the rest of the week
Chams is shorts/boxers or towels and t shirts for men!
Women they class as daring as you want from dresses to underwear! You can bring change of clothes too which lots like to do as they have lockers. For men don't forget flip flops as you don't want to Walk barefoot ideally
Hope this helps
