Final answer:
Moira was wearing a white satin dress, a cashmere shawl, gold jewelry, and her hair was styled with costly scented oil, all of which signified her wealth before buying the car.
Step-by-step explanation:
Before going to buy the car, Moira was wearing clothing that would immediately signify her wealth and social status. She was dressed in a white satin dress, with a cashmere shawl draped around her shoulders, gold links shimmering on her neck and wrists, and her hair carefully styled and held in place by an expensive scented oil called huile antique. This ensemble, especially the expensive huile antique, would have given away her status as 'Rich'.
