Blazers are the classic early autumn layer, but this year a new outerwear style is joining the lineup to help you navigate the switch of seasons: the utility jacket. Inspired by army uniform, it majors on practicality (lightweight, durable, pockets), but it also comes with style credentials. This is the perfect piece to toughen up winter florals and play down frills, or simply team it with denim and cashmere for an effortless off-duty look. Invest wisely now and a utility jacket is destined to become a wear-on-repeat favourite.
