I dress in whatever I feel like at the time.
Some days that's jeans and a T-shirt, some days it's a casual button-down shirt with rolled up sleeves and khakis, some days I like dressing nicely with black pants and a dress shirt (of course, I can only do that when appropriate :-p), some days it's jeans and a light sweater (the kind you can get away with wearing even if it's in the 70s), some days it's jeans and a heavy sweater (in the winter), some days it's jeans and a hooded sweatshirt.....
I think I'll stop now - you get the idea
