Airbrush Makeup for Saturday?!?!?!

Hi!

My wedding is this Saturday

I already have makeup set of course but it is traditional makeup. I managed to get a bad sunburn on my chest and would really like to cover the tan line with an airbrush foundation. I will be getting ready in Plainview. I need to be back at the hotel by 1:00 pm but I could run out somewhere anytime before that. Would any of you be able to help me? Thank you!!!
