Common mistakes people make when folding the pocket square one corner up.
- The corner up is not symmetrical: Weather or not you want to call this a mistake depends on your preference. Some actually prefer that the corner looking sticking out of your pocket breast is not perfectly centered.
- The pocket square doesn’t stay in your pocket and tends to slide down: This happens quite often if you are using a very thin pocket square that is made from fine silk fabric. One way to prevent this is by using a slightly thicker pocket square. Some men even prefer a linen pocket square over a silk one. If you are set on using a silk pocket square, then fold it wider so that it “sticks” better in your jacket’s pocket.
