London Street Style...Fashion's Night Out

The Boys were wearing: Reiss (above) and Topman (below).

The guy above is an Aussie (yay!) and works for Reiss while the guy below works as a visual merchandiser at Topshop/Topman. He had been working since the wee small hours of the morning to get the store ready for Fashion's Night Out and was actually on his way home when I photographed him.

Question for the boys: when does one start to roll the trousers down and begin wearing socks again? Is it heat/weather dependant or trend led?
