These brown and Lovat and check tweeds are certainly lovely! But are they "do-all"?

Here's an example of the potential do-all-iveness (do-all-isity? do-all-ishness?) of a charcoal jacket. All these world-class pipers are wearing black save for Pipe Major Gordon Walker, who is always a cut above in the matters of dress... would a brown tweed jacket work as well in such a social situation?
