Acne Studios - Opt for Acne Studios' cosy blue Keandra sweater – blended with tactile alpaca and wool – as the days become cooler. It's shaped to a comfy oversized silhouette with a V-neck framed by chunky ribbed edging, then finished with a rolled hemline and cuffs for a nonchalant note. Tuck it into voluminous trousers and add colourful trainers for an unstudied edit.
