If it's going to be your first pair, go with the old standby: Levi's 501. The fit is comfortable, the denim is quality and the price is right, so even if you later decide that white denim isn't your thing, you won't have blown three bills.
Today's Buy It Now is the 501 Originals in deconstructed white'14 oz. selvage denim in a bleached-out natural cotton with a straight leg and button-fly. To see another pic of the jeans and for Buy It Now info, see below...
