So were top hats and canes with evening wear, once. And let's be clear: I have nothing against cuffs. The majority of both my suits and my odd trousers have cuffs. I'm sure that suit would look great cuffed. But from the pictures I'd say it looks pretty awesome uncuffed as well. I don't want to sidetrack this thread into some ur-SF debate about traditionalism vs. personal style, so I'll leave it at that.
In the end I agree, it's just personal preference, no rules. I've stated my preference, though I'm curious to see if Baron finds what he's searching for as the combination of a slim-cut leg paired with a chelsea boot sounds intriguing.
