The blue shirt is probably the most underrated piece in a man’s wardrobe, which is strange because most men own several and reach for them constantly. The problem is that not all blue shirts are doing the same job. A pale blue Oxford in a relaxed fit is a completely different proposition to a slim chambray or a deeper navy that reads almost like a neutral. Most men have one version and make it work harder than it should. We’ve been thinking specifically about the blue shirts that earn their place across more than one situation, from the kind you can wear open over a t-shirt on a weekend to the ones that look exactly right under a navy blazer without disappearing into it. Fabric weight, collar roll, and how the color behaves in different light all matter more than most people give them credit for. These are the ones worth building around.
