The plain jumper is probably the most quietly useful thing a man can own, and also one of the easiest to get wrong. Buy the wrong one and you’ve got something that pills after three washes, bags at the elbows, and looks shapeless under a coat. Buy the right one and you’ve got a piece that works over a shirt, under a jacket, or entirely on its own for the next several years without asking anything of you. We’ve been looking specifically at jumpers with no logo, no pattern, no distraction. Just good yarn, a proper fit through the shoulder, and a neckline that actually suits how men dress. Crew necks that sit right. V necks that don’t plunge. Colours worth committing to. The kind of thing that forms the backbone of a wardrobe without you ever really noticing it’s there, until the day you’re getting dressed and everything just seems to work. These are the ones worth the money.
