Thomas de Keyser – Portrait of Loef Vredericx (1590-1668) as an Ensign Mauritshuis

The picture has something of this: people, woman, portrait, wear, man, step, fashion, indoors, model, outerwear, lid, outfit, pants, veil, child, seat, dress.
Perhaps it’s a painting of a man in a black hat and yellow and white outfit standing in a room with columns and a flag in the corner of the room.
