There was a thread about this before, but I wasn't satisfied with the replies. When wearing a tuxedo, which is better - white linen pocket square, white silk pocket square, or none at all? And also, what are the best cufflinks to wear with a tuxedo? (My tuxedo shirt is covered placket, so no studs to worry about matching). I have Dunhill sterling silver square cufflinks with black onyx squares inside of them, are these acceptable? Thanks.
