Change doesn't to be significant or radical to be dramatic. If you're a man who can't be parted from his leather jacket, try a different colour to add a surprise element to your look. You can still wear your favourite jeans and trainers, but a new colour or cut to your normal style will take this look to the next level.
I like to think London Fashion Week serves as a kind of clothes-centric microcosm of the macrocosm of society. Its incarnations, evolution and attendees each season reflect the flighty preoccupations culture places on hierarchy, artifice and worth. Which, given the wealth of design talent showcased, is a real shame.
