What should I wear to a treatment at Hotel Bel-Air Spa by La Prairie?

Travel Guide Inspector

Feel free to arrive at Hotel Bel-Air Spa by La Prairie dressed as you please — upon arrival, you’ll be given a thick white robe and comfortable spa slippers to wear while you’re a the luxury boutique spa. Once a spa attendant shows you where to stow your things in the locker room, you can slip into your robe and relax in the lounge (there’s a separate one each for men and for women) or in the co-ed relaxation room. Most guests wear the robes and slippers throughout the spa, and you are even welcome to keep them on as you eat a post-treatment meal in the private courtyard adjacent to the relaxation room.
