Tell me about them, please. I've never had one or thought about getting one but FI made me stop real tanning a while ago (apparently he doesn't want me to die of skin cancer for some reason...) and I saw a photo of myself from a gig I did last night and it was horrifying. I was wearing a white robe for this one song and I looked exactly like the Ghost of Christmas Past, so now I'm kind of freaking about about how awful I'm going to look in a white (wedding) dress when I am this colour. It was BAD. So bad.
So all I really know about them is that you need to exfoliate first so you don't get darker patches on your dry skin where it soaks up extra colour. Other than that I am clueless. Do you get the machine? A person with an airbrush? How far ahead? What shade? Is it going to rub off on my dress? I don't want to look not like myself but I also really, really don't want to look like a dead bride Halloween costume. Help!
ETA: Here's a backstage photo so you can see what I mean - I did block the faces for the others' privacy and because we were all making very silly faces, but I think you still get the idea on exactly how white I must be.
