What to do about my nails for prom??? Help and advice desperately needed!!!?

Ok, I have my prom tommorow, and I have not yet considered what to do about my nails, and now I have thought about it, it might be a problem. Firstly my dress is white and black, so what color would I paint my finger nails? Or should I just leave them or paint them clear? Secondly is the same problem with my toe-nails, the dress is white and black, so again there is no obvious color to paint them, yet will it look strange for them to be unpainted? (Considering I am wearing black open toe shoes?) :/ Any help or advice would be greatly appreciated!
