Tight pants are de rigueur in menswear these days, but how tight is too tight? We asked an expert, male model Mark Vanderloo, at the launch of his new DKNY men's fragrance campaign last night. "It’s too tight when you don’t have any air in your crotch, do you know what I mean? When your knees are going together and they’re, like, holding the whole thing because you can’t breathe anymore. That’s too tight."
