Prom/formal? Don't wear any strips. Black suit is good unless your dark toned... Then white would be better. If you're going to rent a tux, then a vest and a bow tie that match's your date would be best. If your not renting, then a wear an undershirt that match's your date and a black tie. No date? Then, I would go with a mild to darker red vest and bow tie (I think Asian guys look hot in red). Lol.
