Help with prom colors ?

Hi i was wondering if my date was wearing an orange dress what colors should i wear i was thanking white tux with orange vest and tie. But that is so popular and old. I would like to be the one that stand out but in a good way i need to be clean and sharpe. I also thought that brown would look good with orange or an off white. If you could tell me an color and have a website that i could look at would be helpful.
