I go back and forth...lately, usually some sort of slimmer fitting t-shirt, often with some sort of interesting writing/graphic on it, v-neck. Shorts or jeans, maybe a baseball cap. Maybe a tasteful necklace as a conversation piece. I've found dressing down a little is good, since it looks like you don't care. And looking a tad douchey actually seems kinda good...like it or not, women like d-bags.

What do you guys go with? What works best?
