Among the men's fashion trends for autumn 2023 we are witnessing a great return from the past: that of the cardigan, in its new guise as a must-have. Wear it over a t -shirt or a shirt , like the checked one by The Sartorialist , with a retro feel, and a pair of relaxed-fit trousers. Complete the look with leather details, colorful socks and Paraboot shoes.
