Here are few steps you should take to make sure that a bad spray tan will not spoil your event:
1. If you've never had a spray tan before, make sure that you have a trial few weeks before the occasion. You do not know how your skin will take the solution, especially if you have fair skin. Although chances of going orange are very remote, how would you feel if it happened on the day of your wedding or prom?
2. Don't choose the darkest solution. We would recommend an 6% - 8.5% shade if possible. You want to simply add a "glow" to enhance your features and your attire.
