It all depends what type of spray tan you going for. Also you can choose if you want a normal one or a darker one. I would suggest Fake bake above anything else. Its really good for an all natural tan xxx
I had a spray tan once by fake bake, it was really good. £20. You can choose the shade as well so if you're fair (which I think you are aren't you?) you can choose a lighter shade so you don't look orange! lol When I went it looked brilliant.
Can't afford to do it now so I just use Dove Summer Skin stuff.. its like moisturiser with a hint of fake tan so it builds up really gradually and looks more natural. Dove is the best one of those Ive found... Johnsons was streaky and a bit orange. Might be worth a try if you dont fancy risking a spray tan
