This trend was so ubiquitous this year, especially during Fashion events like the Mercedes Benz Fashion Week, New York Fashion week... Since the entrance of colored socks in various patterns Men have decided to cut their pants at the ankle to reveal their socks or roll it up.
Pegged pants are very manchic and add a bit of ecletic appeal to an outfit. Whether you are rocking Jeans or Khaki's you almost can never go wrong with pegging. It gives this elegant without too much effort look to the wearer.
As temperature falls in the temperate zones we would see less of this trend , unless of course you are somewhere in Brazil or Africa. Looking forward to it next spring, if my fashion barometer's analysis are 90% correct.
