If you're worried about what to wear under your robe at the spa, don't be. Most people are naked under those spa robes, but that's perfectly fine. You can keep your underwear on if you feel more comfortable, or many spas offer disposable underwear for that purpose. What you wear under your robe will largely depend on the services you choose.
If you choose not to wear anything under your robe, that's OK. If you're just getting a massage, your underwear should be enough. This depends on the treatments you have booked and the facilities you would like to use. In general, you should wear bathing suits or underwear.
If the treatment booked requires full or partial nudity, you will be given time to undress before treatment begins. In addition to their robes, there are also towels that will be used to cover some parts of the body that are not being worked on. Going completely naked under a robe is preferable, however, you can keep your underwear (if you are a woman, taking off your bra is essential) if you don't feel comfortable being totally naked. If you're just getting a spa treatment, you can wear your regular underwear; your spa therapist will tell you if you need to take something off so that the creams and lotions get to all the right spots.
You don't need to bring a robe and slippers to the spa, most spas will have them ready when you arrive. Depending on the treatments you receive during your visit, you can also change to a new gown if it gets dirty or damp. As mentioned above, most spas offer plastic slippers or flip flops for you to wear during your visit, and if in doubt, you can always bring your own. It's important to remember that spas want their guests to feel as relaxed as possible, so never be ashamed to express any concerns you have about removing clothes (or any other issues) before or during your visit.
Most spas offer robes and slippers in different sizes to ensure guests feel comfortable and relaxed during their visit. For messy spa treatments that include wraps, mud, and oils, your therapist will offer you a pair of disposable underwear so that yours doesn't get wet, dirty, or otherwise compromised. Spa etiquette is important for ensuring everyone has a pleasant experience. Knowing what to wear under your robe at the spa is just one part of this etiquette. Whether it's swimwear or nothing at all, make sure it's something that makes you feel comfortable and relaxed.
