Stella McCartney's designs are a splurge-worthy investment. Distinguished sustainable practices aside, the UK designer is beloved for her masculine edge and expertly tailored separates. Black and grey are foolproof options for a blazer, but a powerful red one such as this will always remain a special piece in your wardrobe and yield immediate impact when worn. If you really want to turn heads this spring, pair it with crisp white trousers.
