Vest or Waistcoat is back in Fashion since 2010. If you live near a college or a university, you may have noticed something odd — young men are wearing vests again. People love to include vest as part of men's daily wear fashion because it's convenient, useful and quickly draws attention from others. Wearing a vest for mens is not something from 1800 British Fashion, it's happening everywhere. The tradition is more than 100 years old and comes from the same norms applying to suits and blazers. There's no practical reason for it nowadays (except perhaps to give off a more casual flair) — it's just a way of showing that you respect tradition.
