The main aim is being relaxed and comfy when you're at a spa hotel, so casual, non-restrictive clothing is generally the order of the day. While it's likely you'll spend a good deal of your time wearing slippers and a bathrobe, these are usually supplied to guests when they check in. If you'd like to take advantage of the fitness facilities, pack your activewear and trainers. Hoping to loosen those muscles in the swimming pool or hot tub? Don't forget to throw a swimsuit in your bag. Along with toiletries and other essentials, bring some extra clothes too. It's always nice to have a clean, dry outfit to slip into after an oil massage.
