I know a gentleman in his 50's-60's . . . about 5'-6", Southern Italian decent, California bred, lived everywhere, very cosmopolitain. . . . Dresses great by anyone's estimation, with the one quirk that he always wears button down collars and french cuffs.
In fact, he always has custom ordered all of his shirts because he can't actually find them that way anywhere.
No one, including himself, has known anyone else who would even contemplate wearing such a combo, let alone spending the time/money to have them made that way. Until now, I guess . . .
