Just wear decent - not even nice clothes - look ok, shower and have good hygiene, shave properly, trim or shave down there too, be nice and not creepy and have more than 4-5 topics of conversation at hand that you know shit about and aren't just different game franchises or raids you ran.... Ta-daaaa!
