For most guys, wearing a tie is not really necessary (thanks to the pocket cloth) but for some, it’s a must. For those who love ties, it’s not really ideal to put it in the same traditional way. You should learn to play around with your tie and turn it into a bow tie, half windsor, full windsor and even cafe knot, depending on your mood or the occasion of course.
Ties are not only good for formal wear, even casually so, you can wear it. Or if you’re fashion forward and very innovative, you can even use it as a belt.
Some even go as far as turning them into head bands and that’s nothing wrong because in the world of fashion, rules are meant to be broken to bring out something new and stylish.
