A Noughties favourite, the waistcoat has made a storming return to our wardrobes over the past couple of seasons. Cefinn's cashmere-and-wool blend Wesley style is the ultimate trans-seasonal piece.
Wear alone with a wide-legged trouser like Tamara, a cargo trouser or baggy jean for a laid-back, edgier vibe. Or layer it over a T-shirt or shirt if you want more coverage or when the temperature starts to drop. The styling opportunities are endless.
