Rachel Zoe at the Calvin Klein 40th Anniversary Spring '09 Fashion Show.
Multiple tones of blond may be the story here in this long length with volume. The overall look of waves and body make Rachel Zoe look sensuous and captivating.

Karina Smirnoff at the Lupus L.A.'s Hollywood Bag Ladies Luncheon.
At first glace, Karina Smirnoff's formal style appears to be one sided with these flirtateous side swept bangs. However, this large twist that gives this pose a 1920's flashback is actually counter balanced with another, yet smaller, twist on the other side of the back.

The application and placement of these various twists are only as limited as one's imagination. Uma Thurman has a great overall style that is tres' chic for an evening out.

Wrapping her hair around in the back for an updo, Jessica Simpson walks the red carpet with a easy, yet graceful evening style. It presents itself asymmetrically with one side brushed back flat, while the other boasts some loose ringlets, drawing attention to her big, brown eyes.

Curls can absolutely enhance your style and give you lots of fullness, softness and virtual elasticity. Here Lily Allen has had her wish spirals fashioned into random pin-ups for a loose, on the move style as she poses here with a pink signer dress and matching lipstick.

English singer and member of Atomic Kitten, Natasha Hamilton, shows us quite a fashionable updo to pair with a strapless gown. Loose tendrils fall flatteringly on her bare shoulders making this quite a sassy style.

The 2008 Miss Universe, Dayana Mendoza, has her long hair pulled back in the modern take on a formal hairstyle, otherwise known as a low-riding Gothic ponytail. If you are thinking of cutting off your long hairstyle, this is certainly the look to help you determine if you have the features for a short hairstyle.

Here’s Teri Hatcher at the 35th Annual People’s Choice Awards. What do you think about the getup?
Some may consider this formal style to look rather matronly, although it would depend on the person who is wearing it. This is a neat and smooth look on Teri Hatcher, that features asymmetry, giving the elegant low riding bun a new dimension.

Medium hairstyles, like that which Elizabeth Banks has, can still be worn in a formal updo as there is enough length to do so. She has lots of lift off the scalp which makes this elegant style even more exquisite.

The overall shape and placement of a formal style is quite important as it must appear balanced. This elaborate creation on Rumer Willis is quite exquisite and worthy of a special evening out on the town.
