Depending on the type of massage. you will either be fully clothed or undressed to the level of your optimum comfort.  Shiatsu and some sports massage is done completely clothed. Thai pants are provided for Shiatsu sessions. For a full body integrative massage, you should undress to the level you are comfortable; many people get completely undressed. However, if you will be more comfortable during the session if you leave your underwear on, that’s fine. Draping will be provided and modesty will be maintained at all time. The therapist will work around the clothes you left on as best as he/she can. If removing all your clothes makes you too nervous and unable to relax, then you are not getting the optimal benefit from the session.
Your massage therapist will give you privacy to undress and get comfortable on the table. Draping with a sheet or towel is the law in Oregon. The therapist will only uncover the part of your body being worked on.
