It is hard to believe that it's been more than a decade since everyone was lining up at salons to get "The Rachel." It's even harder to believe that the woman who made it famous is now 40. That's right, the lovely Jennifer Aniston hits the big 4-0 today. But if Aniston's recent red carpets (and magazine covers!) are to be believed, 40 is certainly not what is used to be. To celebrate Jen's big day, StyleList took a look back at the Style Evolution of everyone's favorite Friend.

Friends premiered on September 22, 1994 and quickly became a cultural phenomenon. By the time Aniston wore this hideous ensemble to the Second Annual VH1 Honors in June of 1995, her "Rachel" haircut was being worn by women all over America. Luckily her fashion sense wasn't as widely copied.

Jen got it right at the 53rd Annual Golden Globe Awards in 1996 in this timeless and classic nude dress. Unfortunately for her Friends Courtney Cox and Lisa Kudrow, their choices haven't stood the test of time.

Aniston wore this floral frock, and a longer version of her famous "Rachel" 'do, to the 1997 New York premiere of Picture Perfect.

For the 1998 premiere of her romantic comedy The Object of My Affection Aniston wore this very 1990s red dress with matchy-matchy red shoes.

No you didn't blink and miss Jen's dreadlocks phase, those are just product-laden tight curls that Aniston paired with her monochromatic ensemble for the VH1 Divas Live concert in 1998.

After marrying on July 29, 2000 the newlyweds walked the red carpet together at the 52nd Annual Emmy Awards (Prada for her, Hedi Slimane for him).

As Brad and Jen settled into their marriage the duo got increasingly casual about their premiere style. Apparently Aniston didn't even feel the need to wear a bra for the 2001 release of her flick Rock Star.

From a bisexual, knife carrying wild child to a humanitarian activist and mother of six, Angelina Jolie's life has change tremendously in the decade since her unsettling portrayal of Lisa Rowe in Girl, Interrupted catapulted her to superstardom. Not surprisingly, as her personal life transformed so did her wardrobe. With her 34th major film, The Changeling, hitting theaters this week Stylelist took a look back at the female half of Brangelina's style.

In 1986 legendary actor Jon Voight walked the red carpet at the 58th Annual Academy Awards with his unknown 10-year-old daughter Angelia Jolie Voight. If Jolie had realized all that white lace would haunt her forever she may have picked a more subtle dress!

Still a Daddy's girl, Jolie attended the 25th anniversary celebration of Midnight Cowboy (her father's most famous film) in 1994 wearing leather instead of lace.

With two major films under her belt, Hackers (where she met her first husband Jonny Lee Miller) and Foxfire, 22-year-old Jolie boldly rocked a shaved head and a little black dress at the premiere performance of Fedora in 1997.

A practitioner of method acting, Jolie was back in a dark place for her breakout role in 1999's Girl Interrupted. The disturbing intensity she brought to the part carried on to the red carpet for the film's L.A. premiere.

At 24-years-old Jolie had two Emmy Awards, two Golden Globes and in 2000 she added an Oscar to her trophy list. Unfortunately her Elvira-like outfit and a proclamation of love for her brother garnered even more attention than her achievement.
