The open collar shirt is doing more work in most men’s wardrobes than it gets credit for. It sits in that space between dressed and undressed where a lot of actual life happens. Dinner that isn’t quite formal. A Saturday that starts casually and ends somewhere better. The problem is that most shirts only commit to one mode. They’re either cut for tucking in or they hang like a sack when you don’t. The collar either collapses without a tie or it sits stiff and wrong when you leave it open. We’ve been looking specifically for shirts that handle both situations without asking you to compromise. The things we’re looking for are collar roll, fabric weight that holds without stiffening, and a hem length that works either way. Prints and plains, Oxford cloth and poplin, casual cuts and ones that can pass for smarter. All of them reward the top two buttons being left undone. That is not an accident.
