This is a good question for several reasons. People want to know, most often for spas, what they should wear to ensure they are prepared and comfortable for the service that they are about to receive. Some people may ask this question of salons in the case of needing a button-down shirt instead of something that pulls over the head, but generally, most spas and salons will say “come as you are”. Still, you’ll want to let people know either way.
