How are Mr. and Mrs. Monarch described in the story, The Real Thing, from the collection, Tales of Henry James?

Major and Mrs. Monarch are supposedly "the real thing", born to gentile upper-class British life. They look the part. Both are tall, good-looking and have excellent posture. The major has a full moustache, and a hand-tailored suit. His wife is well-groomed and beautifully dressed. They are accustomed to visiting friends at their country houses. Now in need of money, they appeal to an illustrator to use them as models for his work, with unexpected results.
