Band: Guns N' Roses; Slash's Snakepit; Velvet Revolver

It's impossible to make a list like this and not include Slash. The man does stick to a uniform, but at least it's a versatile and good one. As long as the top hat, shades, and cigarette are there—you know it's Slash. More iconic than actually stylish-after all, he hardly ever wore a shirt, his consistency throughout his career is admirable.
