We're smitten with Burberry's new wave of youthful trench coats - and this laminated layer in Modern Stewart Royal Tartan is topping our list of new-season essentials. The bold red and black check is easy to take through all seasons while the glossy overlay is a high-tech and statement finish - but one that's easy to maintain. Knot the belt over tailored pants or cuffed denim, it will go with any look.
