Wearing a handkerchief with Neck Ties as well as Bow-ties is a perfect way to add more personal character to your outfit. When choosing what type of pocket square to wear think about the occasion and about how formal of an event you are dressing for. For very formal occasions you want to wear a classic white pocket square.
Once you have your pocket square picked out and decided what type of fold best suits your outfit, start by cleaning your hands, as well as the area used to fold your hanky. Keep in mind that handkerchiefs can be made from silk, especially so-called Thai silk, as well as cotton and linen.
