Far from being just a festive trend, metallics were spotted on the runway as early as last spring. From Gucci and Versace through to Chanel, silver was a theme that dominated, with Isabel Marant showing highly polished trousers that prompted fashion editors to declare the look a key trend. Fast forward to autumn/winter and the high street has caught up. Silver, the colour of the season, feels fresh after seasons of saturated brights.
