How to wear denim at work and not look like you’re lost on your way to casual Friday:

We all know that old rule: For fear of looking like a slouch, keep your jeans out of the office. But as with all things swept up in a spring refresh, the way we approach denim and its functionality in our lives is changing—and the timing couldn’t be better. In the wake of a more wearable, approachable, and less peacocking-focused take on dressing, a flock of season-perfect denim pieces came down the spring runways, with styles shying away from the usual weekend-heavy wear-and-tear and geared up towards polish, whether as neatly tailored sheath dresses and pencil skirts or the glistening bedazzled boyfriend jeans at Dolce & Gabbana and raw jumpsuits at Chloé.

What makes outfitting in denim at work especially exciting is the fresh sensation it brings—the simple incorporation of the usual weekendwear into your nine-to-five feels rebellious, utterly easy, and even a tad bit naughty, if you’re sneaking a particularly trouser-like pair of jeans in to the mix. (Plus, it opens up a whole new section of your wardrobe.) Fit, performance, and fashion are the name of the game, and this spring we have several heavy hitters that we plan to keep on equally heavy rotation.

Here, a slew of season-perfect denim to wear to the office and beyond that’s high on livability, cool, and classic professionalism—we promise, nobody will think you’re lost on your way to casual Friday.
