Same way you differentiate between different stuff in the same class--quality, style, that sort of thing. I've never worried about that part of things, though, because the jump from "no suit" to "well-fitted suit" feels bigger to me than "well-fitted suit" to "well-fitted, expensive suit", and I mostly wear one because I like them, so I haven't indulged.
