Underlining its versatility, denim is also a great choice if you’re looking for a smarter, preppier look. Pick out a pair of stonewashed jeans and match with a pair of polished loafers, a blue blazer and a crisp blue shirt, open-neck or with a tie. A slim pair of jeans is best — as for all looks, avoid the super-tight style unless you’re searching for a rock & roll look. Jeans in this look should be ankle-length and shouldn’t show your socks, so try a pair of no-show extra-low socks with your loafers.
