Email: Jeans to tux [EH]

Why do women always say their ideal is a man who can go from blue jeans to a tux? What man ever thinks like that (in terms of being a clotheshorse)? What man ever does that? What man ever rents a tux for anything but his wedding -- and even then only because he must -- much less owns one so he can "pop into" a tux (as if he goes to such events often)? The only men who need a tux to attend a gala as a planning committee chair or a VIP are doctors and lawyers, as a rule. Am I wrong?
