Highlights in your hair can look very nice at night. Evening lighting tends to increase the contrast--highlights look lighter and dark hair even darker.

Jennifer has one main thin blonde highlight in her long brown hairstyle. She also has lots of other highlighted streaks in different shades of brown elsewhere.

This is one of the better down hairdos we've seen since prom 2007. Jennifer Garner wore this hot style at the MTV Music Awards.

If you'd like a down hairstyle for prom, but tend to think down straight styles aren't really formal or special enough for prom, or a little bit boring, fresh hair coloring might give it some character.

This style is lightly teased with moderate highlighting--easy but still attractive. It's a good choice for a sensible girl who doesn't want to fuss too much for prom.
