Never underestimate how useful a black blazer can be. It instantly smartens any outfit, it goes with everything, and it provides a much-needed extra layer of warmth when cold weather hits. If we were to write a definitive list of fashion essentials, a black blazer would probably be near the top of the list. But don't be fooled into thinking this is a boring piece of clothing. While there are plenty of timeless classics out there, Supertrash has put a new spin on the look by adding a shimmery herringbone texture and a leather trim to the Jockey Blazer (£150). The details give the jacket a glamorous edge, making it the perfect partner for party dresses and evening looks. Or just throw it on with your most battered pair of jeans to bring them back to life.
