Men's sweater vests are the epitome of versatile elegance, seamlessly bridging formal and preppy aesthetics. For a polished look, pair a v-neck cashmere sweater vest with a crisp button-up shirt, tailored trousers, and a tie for timeless sophistication. To channel varsity charm, layer a men’s knitwear vest over a collared shirt and complete the outfit with a blazer for a sharp, collegiate-inspired ensemble. A button-up sweater vest adds a refined touch to office or evening wear, effortlessly elevating your outfit while providing warmth without bulk.
