Maybe look up the community on the Internet and phone them. (From a pay phone? ). I am sure they deal with visitors and guests all the time who are very new to this, and will be happy to answer your questions.

You could ask your BF in a joking way - "If I go there without clothes, I'll FREEZE!" HOPEFULLY he will laugh and say - whatever, you'll have your answer.

Just practice looking into people's EYES....
