This is the shirt you reach for when a jacket is too much and a plain overshirt is not enough. It is a shacket in a charcoal herringbone that changes with the light: indoors it reads almost black, and in natural light it reads brown, with the zigzag weave showing as you get closer. Wear it open over a tee, or buttoned over a fine knit.
Wear it open over a navy or grey tee with dark denim and brown boots, or button it over a fine turtleneck and put an overcoat on top. Charcoal herringbone sits easily next to navy, grey, olive and cream, so it will not fight with what is already in your closet.
