Dress down your black trousers with a casual T-shirt or a cozy knit sweater. Tuck in your top and add a stylish belt for a more put-together look. Complete the outfit with fashion sneakers or loafers for a comfortable yet chic appearance. For a night out, pair your black trousers with a silky top or matching waistcoat and opt for a statement necklace or bold earrings to add glamour. Complete the look with strappy heels and a statement bag
