I am in a wedding in 4 days (on Saturday) and was hoping to get more color over the weekend to even out my tan lines; however, that didn't quite happen. I've gotten a professional airbrush spray tan before and it turned out nicely, but I'm worried about it coming off on my bridesmaids dress (or even worse on the bride's) due to the heat of a July wedding. If I got my spray tan Wed, should I be okay for Saturday?
