Here are two ways you can fold yours.
Choosing the right material is important but not crucial – it all depends on what look you’re going for. Cotton squares are the most popular and generally have the most contemporary designs. Linen squares add great texture and look great in the warmer months. Silk squares look sophisticated when puff-folded into your breast pocket.
There are no hard and fast rules for which colours to use, but it’s worth keeping in mind that the traditionalists among us prefer a white pocket square for business suits. Blue and pastel colours will do the job just as well, though. Best to save your bright patterns for evenings or a special occasion. Your pocket square should contrast with your tie rather than match it as well as complement the colour of your shirt. If you’re feeling brave, go for a pattern clash.
