Mathilde Loisel is depicted as a superficial, materialistic woman who regrets marrying a humble clerk and dreams of living a privileged, aristocratic life. Guy de Maupassant writes that Mathilde Loisel would often daydream of antique silks, delicate meals, and gleaming silver at dinner time and was envious of her rich friend who she refused to visit. Her delicate financial situation bothers her, and she desires to have luxuries that other women of her status would never notice.
Madame Loisel's materialistic nature is also revealed when Guy de Maupassant writes that jewels and clothes were the only things she loved. She is solely focused on her social status and attached to objects, which she imagines will bring her happiness. Despite having the necessary accommodations, Mathilde Loisel is not content and is tortured by her living situation.
She is an entitled woman who genuinely believes she deserves to experience the luxuries of the upper class. There is nothing her lowly husband can do to please her, and Mathilde Loisel demonstrates her ungrateful personality by immediately rejecting the invitation to the ball. Rather than appreciate the rare opportunity to mingle with elite members of society, Madame Loisel despairs at the fact she will have nothing expensive to wear. Unfortunately, she ends up borrowing a fake diamond necklace from Madame Forestier and loses it.
