Everyday Tee with Vertical Print
A plain tee with a vertical print running down it, unlined and uncomplicated, for wearing under everything else.
Not every shirt needs a case made for it. This one is a tee, the print runs vertically rather than across the chest, and there is nothing else going on. Black is the colour, and a black tee is the single most useful thing in a work wardrobe because it goes under a flannel, under a hoodie and under a jacket without ever needing to be considered.
Buy it in the size you normally take and buy more than one. Shirts like this get worn until the neck goes, and the honest expectation is that it becomes a work shirt, then a weekend shirt, then the thing you keep in the garage. That is not a criticism of it; that is the whole life cycle a good plain tee is designed for.
