The Duke of Marlborough in Garter Robes Sir Godfrey Kneller (1646-1723)

The picture has something of this: people, wear, woman, veil, portrait, sword, Renaissance, dress, cape, costume, sash, lid, armor, music.
Perhaps it’s a painting of a man in a white suit with a red, white, and blue coat and a black hat with a feathered hat on his left hand.
