The 65th annual Primtetime Emmys will broadcast live on Sunday and one of the most highly anticipated part of the event is the celebrity arrivals on the red carpet ahead of the ceremony.

Enstars compiled some of the best and worst fashion worn by the television actresses and movie stars at least year's 2012 Primetime Emmys.

Bold bright hues, warmer versions of pale pastels and jewel tones were the top fall 2012 fashion trends that were prominent on the red carpet.

Two of the night's winners- Homeland star Claire Danes and Modern Family star Julie Bowen-- stood out most for wearing a dress in a bright yellow shade. Actress Julianna Moore's floor-sweeping long sleeve canary yellow gown by Christian Dior Couture was also considered a knockout last year.

Reality television star Padma Laskshmi and actress Leslie Mann chose another shade of the bold bright variety in a citrine orange.

Pastels were best represented by New Girl actress Zooey Deschanel. Her pale blue Reem Acra strapless gown landed her on best dressed lists as did Heidi Klum's. The Project Runway star flaunted her legs in a sexier version of pale blue dress that featured thigh-high slits on both sides. The slits were so high it was open all the way to her waist.

Sofia Vergara chose a warmer version of pastel with a beaded gown in a flattering shade of seafoam green. Unfortunately for the Modern Family actress she got more attention than she intended when she suffered a wardrobe malfunction. The back of her dress split wide open while she stood backstage and she shared the cheeky moment on Twitter.

Last year's top color trend, blood red, was worn by many stars including Julia Louis-Dreyfus and Tina Fey who impressed fashion critics with her choice of a strapless Vivienne Westwood dress complimentary shade of wine. CBS' Two Broke Girls star Kat Dennings flaunted her cleavage in a formfitting blood red dress that flattered her curves.

The most disappointing dress that came in the popular hue was worn by Big Bang Theory star Mayim Bialik. The mother-of-two's frumpy gown provided by designer Pamella Roland disappointed with its unflattering fit.

Some of the other worst dressed looks worn on the red carpet last September featured floral prints. ABC's Modern Family actress Ariel Winter and The Good Wife star Julianna Margulies landed on the worst-dressed lists when they wore botanical prints at the swanky event.

This year's 65th annual Primetime Emmys will broadcast live on Sunday, Sept. 22 at 8 p.m. EST on CBS.
