Blue is doing a lot of work in most men’s wardrobes and it does not always get the credit it deserves. The right blue jumper sits across more outfits than almost anything else at this price level. Navy over a white shirt. Cobalt with grey trousers. Washed indigo with darker denim when you know what you are doing. The problem is that at lower price points, knitwear tends to let you down on yarn quality or construction, and you end up with something that pills after three wears and loses its shape by Christmas. What we have been looking for here are the pieces that avoid all of that. Jumpers where the weight is right, the colour holds, and the finish does not give away what you paid. Some of these are high street, some are lesser known brands worth knowing about. All of them wear better than their price tag suggests. Blue this useful should not cost this little.
