I have a spray on tan question?

I have decided to get a spray on tan for my brothers wedding since my legs wont tan to save my life. lol. anyways, what do you wear when you get spray tanned? i was looking on line for places near me and this one website said to wear something that you will be comfortable in in front of others because there will be a erson in there with you but i thought you were in a booth by yourself? not comfortable with being half naked in front of others.
