Snapshots of Françoise Hardy wearing a trench with white sunglasses in the '60s and Alexa Chung today are proof of the enduring appeal of Burberry's iconic coat. Part of the brand's instantly shoppable runway collection, this design is cut from cotton-gabardine - a waterproof cloth invented by the founder in 1879 - but is freshly updated in navy, dark-green, yellow and white tartan. It's detailed with smooth black leather buckles and horn buttons.
