Red is one of the key colours for spring/summer 2017, and although the most talked-about colour combinations this year are red and blue as well as red and hot pink, Sienna Miller showed at Paris Fashion Week this weekend that red looks most striking when worn head to toe. At a fashion party, Miller wore a slinky red slip dress by Nili Lotan, which she paired with a matching scarlet leather biker jacket. Sienna Miller is one of our ultimate style pinups, and while we have long considered a leather biker jacket a wardrobe staple, she's making us want a classic biker in a bold postbox red too. Thankfully, Topshop has an excellent style in suede for £165.
