The '62 is the classic style of Chaplin's mustache. It's the one you see in most of his films. A thick and wavy mustache that says, "I'm a sophisticated gentleman with a penchant for crime."
The Thinny is for those who want to make a statement. It's a thin and sleek mustache that says, "I'm a man who doesn't take himself too seriously, but still manages to be intimidating."
The Handlebar is for those who want to go full-on caveman. It's a thick, bushy mustache that says, "I've been stuck in a time loop since the 70s and I like it that way."
