You can never go wrong with the classic, Turtleneck top, glases (not optional), sneakers, Ulysses.
There is a more modern way though, bring a travel chessboard and do random moves, then look at your phone type somethgin, wait, and then make another random move.
I don’t know if it’s because i’m not a native speaker, but i consider people who use “male” and especially “female” instead of “men” or “women” very very weird at best.
