The main aim is comfort and practicality when you're at a spa hotel, so loose, casual clothing is the choice of attire for most guests. While it's likely you'll spend much of your time in a robe and slippers, these are often supplied to guests when they check in. If you want to take advantage of the exercise facilities, pack your sportswear and trainers. Hoping to kick back and unwind in the swimming pool or hot tub? Be sure to pack your swimming suit. Along with toiletries and other personal items, bring extra clothing with you too. It's good to have a clean, dry outfit to change into after an oil massage.
