Question for sunless tanners?

My prom is on Friday and I want to be very tan because the dress is white and I am Caucasian and Asian (Japanese) so I am pretty light skinned. I have never gotten a sunless tan before.. I heard that airbrush tanning is pretty great because you can take a shower before the event and you'll still be tan and it won't rub off on your clothes and I've been reading reviews for airbrush tanning in my area and the one bad review that it had was something about being orange and blotchy and that she got one with a bronzer with it. so my question is, bronzer or no bronzer?
