Blue is the most useful colour in a tie collection and most men already know this without quite being able to explain why. It works with navy, which should be a contradiction but isn’t. It holds its own against grey, softens a charcoal suit, and gives a white shirt a reason to exist. The question has never been whether to own a blue tie. It’s which blue, in what fabric, and with how much going on in the weave or pattern. A flat mid blue in silk does one job. A rich petrol in a knitted wool does another entirely. We’ve been collecting and wearing blue ties long enough to have opinions about all of it, and these are the ones that keep getting picked off the rack ahead of everything else. Some are understated. Some have a bit more to say. All of them are worth the hanger space.
