You will usually be asked to undress down to your underpants/boxer shorts. This is to allow for access to your back and leg areas for massage. If you are only wanting your back massaged, then you may keep loose fitting trousers on that can be lowered over your buttocks. Please be aware that under NO circumstances do we allow clients to be naked for reasons of hygiene and professionalism, and we always use towels for covering the areas of your body we are not working on in that moment for your comfort.
