There are a handful of high-street and contemporary brands that can, quite frankly, get away with murder. And by murder, I mean creating pieces with all the polish and expensive-looking details of designer buys, sans the four-figure price tag. The three I return to again and again? Zara, COS and Reformation.

Zara has mastered elevated basics: cardigans updated with frog fastenings, cinched-waist shirts and barrel-leg denim that could easily pass for something pricier. COS, meanwhile, has perfected the kind of quiet restraint associated with The Row, from sculptural accessories and soft cashmere to beautifully cut tailoring. Then there's Reformation. The cult Jadey cashmere jumper and Clara cardigan are obvious standouts, alongside fluid satin trousers and perfectly cut straight-leg denim. Together, these three brands make building an expensive-looking autumn wardrobe remarkably easy.
