The denim shirt is much more versatile than you imagined. Having evolved from its days as a rugged favourite, it has been given a second lease of life, and considerable amounts of shelf space. This time around, instead of just keeping it aside as off-duty gear, work it in with officewear too. Pair a light slim-fit piece with chinos and a blazer when you’re on the clock. For weekends, use it to master double denim, or throw on a heavier one over a crew-neck T-shirt to replace a jacket. Need to dress up a bit? Pick a printed version.
