Do you wear clothes in a spa?
Spas want their guests to be as comfortable as possible, so if you would prefer to arrive in non-restrictive garments, such as gym wear or lounge wear then that will be absolutely fine. After this, you will change and spend most of your time in a robe anyway. It’s worth taking a spare swimsuit so you have a dry one to change into. If you’re just having a spa treatment, you could wear your usual underwear; your spa therapist will tell you if you need to remove anything so the creams and lotions reach all the right bits.
