This is a "whiteface clown" costume, with the face painted white (though he here wears a mask with this makeup instead of applying it directly to his face), features enlarged and every movement grander. He wears an oversized "suit" in one piece, with large ruffles on ankles, sleeves and around the neck, and there's also oversized "buttons" in front. He wears a coloured wig and a tricorn hat or cap with tassel, often white gloves, and the already mentioned white halfmask with red cheeks and defined eyes. It is a "grotesque clown", in the original meaning.
