"Your coat is the most powerful piece that you can show. It's the first thing that people will see, so it's important to have a really beautiful one in your wardrobe," says stylist and influencer Diletta Bonaiuti in PorterEdit. Not only does it need to look great, it has to be well made too - which is where Mackintosh really shines. This one has been crafted at the label's UK workshop from Storm System® bonded wool sourced from esteemed house Loro Piana. It's cut for a slightly loose fit but has a classic trench belt to cinch.
