A big thing with not looking like you meet one (or more than one) of Valerie’s criteria, is how you pair it with footwear/top. Don’t pick a matching set, and don’t pick just alternative similar tops! Looks terrible. Relatively quick dry sports T Shirts (like what you can get from Under Armour, Nike, North Face, etc) look much better, as can polo shirts. Avoid the cargo pockets if you can too-not always easy. And most definitely avoid zip offs…worst look in history…garanteed way to look like a loser while travelling…
A good trick to getting your clothes to dry quicker overnight, is to wrap them up in a towel and stand on them. Even the quick dry stuff, makes a difference. Of course this assumes you are staying in a place with a towel.
