Kristen Bell on The Red Carpet in Pretty Sky Blue Evening Dress

Images of Kristen Bell in gorgeous light blue ball gown with half-up hair do at the 59th Emmy Awards in LA.

Oh. My. Gosh. What an amazing evening strapless dress Kristen wore to the biggest TV star-studded event of 2007.

Pale blue looks wonderful with blond hair, so Kristen looks great in this color scheme on the red carpet.

As you can see from the other formal event hairstyles she wore, Kristen likes a kind of slightly informal or semi-formal look--sort of loose, sort of messy.

Messy can be sexy, some girls think, although we haven't asked the boys yet.

Still, not all teen girls are comfortable with a more relaxed or casual look for a night as traditionally formal as prom.

If it fits your personality, and your high school isn't too conservative, a loose prom hairstyle might be perfect for you.

Half-up loose formal hair styles often look charming and project romantic flair for any woman at any age.
