What image do these details Mme Loisel, "paint" of the life MMe Loisel desires?

Mme. Loisel's greatest concern is her own social class, especially the way she is perceived in society in virtue of her appearance and attire. She dreams of a life of extravagant luxury that will make her happy. It is her focus on social class that causes her to borrow a necklace to wear to a party to which she and her husband have been invited; in an ironic twist, this very necklace results in them becoming even lower in social class when they lose it and must work to pay for a replacement.
