An Officer in the East India Uniform of the 74th (Highland) Regiment John Opie (1761-1807)

The picture has something of this: lid, people, man, veil, wear, portrait, costume, cap, jacket, facial hair, vest, mustache, music, sash, outerwear, outfit, weapon.
Perhaps it’s a painting of a man in a red uniform with a black hat and a cane in one hand and a black and white hat on the other hand.
