A massage is most effective if the client undresses completely. That way the therapist can work without a bra strap or waistband interrupting strokes, and without worrying about accidentally staining your clothing with oil. But the most important thing is for you to feel completely comfortable and ready to relax. During the massage you will be covered by a clean sheet. The therapist will only uncover the area he is working on.
Some clients prefer to keep their underwear on.
Some female clients request a towel to cover their chest. Every client has their own level of modesty, which will be scrupulously respected. After experiencing the professional atmosphere of a few sessions a client may feel comfortable enough to undress completely. But the choice is always yours. Massage oil is used to reduce friction from the skin during the massage strokes.
