Despite the fact that the iconic two-tone Chanel pumps were designed 60 years ago, they're still one of the most coveted pairs of shoes. Every season, a new iteration comes out and immediately they sell out. But what, we hear you cry, makes them so perennially popular? Designed in 1957 by Coco Chanel, the two-tone shoes, which initially were a slingback, were meant to mimic men's shoes at the time. It was also considered to be a universally flattering style. Thanks to the contrasting-coloured toe, the shoes both made the foot look smaller and the leg longer. Clever, eh?
