like previous posters stated, it depends where the date is taking place,,dinner or lunch at a nice establishment- khaki pants(black or tan) a nice polo shirt, cant go wrong for that. if it is somewhere like a pool hall, or baseball game, or sports bar type maybe a clean pair of jeans and a nice t-shirt. Or if is a walk along the river or something athletic maybe shorts and any t-shirt, some running shoes. and if is a sports type date the appropite equipment, running shoes, soccer cleats, etc... the most improtant thing to remember about a first impression is you only get to make one. After you start dating you wont be the one making the decision what to wear anymore,,it will be her. lol
