Does anyone have any advice for a first time LARPer?

In October, I will be attending my first LARPing event (for those of you not in the know, LARP stands for Live Action Role-Playing) and I was just wondering if anyone has any good advice for me. I’m looking for any general advice, but also advice specifically for female LARPers. I know it’s not really the kind of thing that many girls do, which is why I’m looking for advice.
