It mainly depends on the projects you do. If it is full-body massage, such as essential oil massage, detoxification massage, lymph combing and so on. You should take off your coat and wear only underwear. If it's facial beauty, you don't have to take off your clothes.

The beauty salons I have been to generally have large bath towels and electric mattresses. When I go in and out, I can wrap a towel and massage myself in bed without catching a cold.

If it is a foot massage, there will usually be loose massage clothes for the guests. You just need to change them. Like a big class or something.
