And what is it? Something that you like and that you wear nearly every day, with which you combine any other item in your wardrobe? It could be anything from a bow-tie, a special shirt-collar-shape or even a colour that you prefer to such obvious items as strange hats or pipes or (sun-) glasses. p.s. replies such as 'my trusted old pair of underpants' will be unavoidable, yet they bore me: I know them all and also have absolutely no sense of humour if something is not funny!
