The Dior Institut at the Plaza Athénée is a luxurious spa ensconced in a sumptuous hotel located in one of the most splendid cities in the world – Paris. So it shouldn't come as a surprise that the Institut is a nominee for a Luxist award in the best day spa category.

The connection between the Plaza Athénée and Christian Dior dates back to 1947, when the fashion house's namesake and founder chose the hotel as a place to photograph and showcase his models. Soon he began to invite his best customers there for lunch, or eat by himself in a private dining room. Dior even named a couple of his designs "Plaza" and "Athénée."

The Dior Institut was established to promote Christian Dior's goal to make women "prettier and happier," with a focus on reversing the effects of aging. The spa boasts five individual treatment rooms, including a VIP couples' room. There is also a fitness center, a sauna and a steam bath on the premises for clients to relax in after receiving treatments.

The typical treatment at Dior begins with a "Lifting 3D" massage, designed to raise energy levels and transform the guest's posture. Next, micro-abrasion revitalizes tissues and skin. Finally, Dior's anti-aging potions are applied to stimulate, reoxygenate and decongest skin. What better way to prepare for a night on the town in the City of Lights?
