Mila Kunis in November of 2010 arriving for the “Black Swan” closing night gala screening at the AFI Fest held at the Grauman’s Chinese Theatre in Hollywood. She stepped out onto the red carpet in this gorgeous black silk chiffon dress by Oscar de la Renta. Her long dark hair was parted to the side and pulled back into a very curly, very elegant ponytail. She had just a little height at the crown of her head to give it a very romantic look. She chose to wear drop diamond earrings. This hairstyle would be perfect for prom night.

Mila Kunis in September of 2009 arriving for the 61st Annual Primetime Emmy Awards at the Nokia Theatre in Los Angeles. She looked beautiful in this cranberry colored dress. Her diamond jewelry was beautiful. Her updo hairstyle was almost regal. It was a very elegant look with the front of her dark hair parted to the side and then brushed straight back at the crown and pulled back into a chignon. What a beautiful hairstyle to copy for a prom style!

Jennifer Love Hewitt in February of 2008 arriving for “The Envelope Please” 7th Annual Oscar viewing party in Hollywood. This is an amazing updo hairstyle for long hair. She wore her dark brown hair in this lovely updo, her hair parted to the side in front to drape across her forehead. Then at the crown her hair is pulled straight back, with a little height and then twisted a little on the sides and then finally placed in a chignon a little higher up on her head. This is a classic look, very elegant. What a great look for prom night!

Jessica Simpson in October of 2007 arriving for the Operation Smile 25th Anniversary Gala at the Beverly Hilton Hotel. Her long blonde hair was arranged in a very pretty hairstyle. This would look gorgeous for prom. The back was simply put into a very low ponytail, right at the base of her head. A piece of her own hair was use to wind around the band. Two small strands were pulled from the front to crisscross on the back of her head. Her long bangs were parted to the side and there was some height added to her crown. Her hair was slightly wavy at the end.
