Inject a little colour into your wardrobe with our mens blue jumpers and mens blue cardigans. Not only blue the perfect alternative if you're addicted to all-black everything, it's the quiet workhorse of knitwear - it also just looks great on everyone as a universally flattering shade. Pair a men's navy blue jumper with earth-toned chinos for an office-ready look that's set to impress everyone from your boss to your barista. Change things up for the weekend: try graphic tees with mens blue cardigans, casual cargo trousers and crisp white cupsole trainers. Equal parts sporty and laid back, blue really is the next big thing for knitwear - make sure you check out our edit of fresh options to swap into your line-up.
