We wandered through Marie Antoinette music-rooms and Restoration salons
Marie Antoinette and Restoration are two styles that are associated with ostentatious wealth. Marie Antoinette, as pictured below, is characterized by gold embellishments and colorful patterns that exemplify grandeur…
…whereas Restoration, as pictured below, refers to an English style that incorporates Dutch and French influences and focuses on exotic and ornate detailing.
Gatsby uses both styles because they make him not only appear to be very wealthy, but it makes him seem very culturally attuned. He obviously knows the two styles well enough to incorporate them into his house, which makes him all the more appealing to people of old wealth, like Daisy.
