Christina Aguilera with Long Formal Ponytail and Short Bangs

A ponytail hairstyle, of course, is the epitome of casual style. But it can also look fine on elegant occasions when you wear a special formal dress.

Christina chose it on the occasion of the launch of her new fragrance. She also had a ponytail for a celebrity event back when she had black hair (see right menu).

It's fairly rare for celebrities to wear ponytails at major Hollywood functions, but they are so youthful, they could look nice at prom.

However, you may want to elevate your style with glamorous jewelry, special earrings, or formal hair accessories to look and feel less plain and more glam.
