Today I am wearing an ash colored glen plaid, 1-button, peaked-lapel suit; a white cotton shirt with French cuffs; a textured ash colored silk tie; a white linen pocket square; a pair of black cap-toed shoes; and a vintage Rado Voyager Automatic in Stainless Steel.
Please note that a 1-button suit is considered to be a fashion-forward suit and not suitable for normal office wear. I can get away for two reasons: first, is that I am a CEO and can get away with it; and second, that very few people over here understand about suits. If you are going to face an interview, I would recommend that you wear either a three or two button suit in conservative colors.
On the other hand, just don’t give a damn and wear whatever you want.
