What was Margaret Macomber's profession?

Margaret, or Margot, Macomber is a kept woman. She doesn't love her husband; indeed, she doesn't even respect him. But she enjoys the opulent lifestyle that comes with being married to a rich man. The Macombers have been married for eleven largely unhappy years. Five years before the story takes place, Margot had commanded up to $5,000 a time for endorsing beauty products. This would suggest that Margot had worked as a fashion model or perhaps an actress—certainly some kind of profession in which she could trade on her beauty. Indeed, Margot's extraordinary beauty is the only reason why Francis married her in the first place. She knows her husband regards her as a "trophy wife," and that, combined with his perceived weakness and cowardice, is what makes her treat him with such contempt.
