The main goal is comfort and practicality while you're at a spa hotel, so casual, non-restrictive clothing is the choice of attire for most guests. While it's likely you'll spend much of your time wearing a bathrobe and slippers, these are usually supplied to guests when they check in. If you'd like to take advantage of the resort's exercise facilities, pack your workout gear and trainers. Hoping to loosen those muscles in the pool or steam room? Don't forget to throw a swimsuit in your bag. Along with toiletries and other personal belongings, bring some extra clothes too. It's always good to have a fresh, clean outfit to put on after an oil massage.
