A white pocket square is something every man needs to have in his wardrobe. This is not up for debate, if you haven't got it, just get it. Adding a silk handkerchief is the quickest, easiest and most common way of spiffing up your suit, and if you're used to wearing a suit with only a tie, start your pockerchief carreer with the solid white. Briljant White obviously works with everything so extremely versatile and fit for use both at formal and informal occasions.
