What to wear for a massage?

In the clinics I work in, clients are told to wear whatever is comfortable for them. When a client is brought into the treatment room, the therapist will instruct the client to undress down as far as they are comfortable. Most clinics have clients leave underwear or panties on and take everything else off, including jewelery. Spas may have a changing room where clients will undress and put on a robe to go to their treatment. It is individual based on the clinic. If in doubt, always give the clinic a call and ask them what you should wear. They will be more than happy to explain their procedures.
