Do spray tans actually work? I have never done one, and I am so pale I think that they would make me look orange. Are there different shades of spray tan? I am going in September, and I would love to look tan, as opposed to my normal ghost shade. I would at least like to have some color right after the summer season

This is when I usually hibernate because I burn so easily.
When getting a spray tan, do you have to get naked, or can you wear a swimsuit or something. I am pretty modest, and the naked thing embarasses me...ALOT
Thanks for any info!
