Rather than carry two coats you could carry two sets of button.
You'd have holes in your jacket, right? So you couldn't go "buttonless". So yeah, sure you could put on black buttons. Now, whether I'd consider that "day wear" or not is another question.....it will still be black.

Go geta tweed jacket and modify it. That is definitely day wear.
