The most stylish celebs, decked out in their favourite Chanel outfits, showed up last Thursday to celebrate the opening of the new Chanel Boutique on Robertson Boulevard in Beverly Hills.

Which five starlets wore Chanel best though?:

At 5 is actress Malin Akerman who looked fashion forward in a black glittery all in-one suit with a plunging neckline. What a daring look! This could look dated quickly so I'm not sure I like the 70s style Farrah Fawcett flicks with it, but the sleek, silver clutch is lovely.

At 4 is one of my very favourite actresses, the beautiful Rachel Bilson! I love how she's made her new fringe versatile by wearing it pushed to the side and I love, love, love her acid orange clutch.

The frilled shift dress is cute but it drowns Rachel's tiny frame a little.

At 3 is Michelle Trachtenberg, who for some reason unknown to be, Chanel did not want people to know attended the store opening! Apparently they asked photo agencies not to post photos of her at the event, but wisely they ignored those wishes!

Michelle looked chic in a high-waisted, grey knee-length skirt with a classic black vest tucked in and a pretty silver belt to accessorise. I wonder if she'll wear Chanel any more??

Youngster Emma Roberts brought some much needed colour to the event with a stunning, floral print halter-neck maxi dress. The style, the colour, the print........I love it all! And it fits her perfectly. This look is just the right amount of fun and stylish in one and the little gold clutch adds some glam.

And at number 1 is my favourite Gossip Girl, Leighton Meester! She looked elegant and gorgeous in a little black Chanel dress with a fitted bodice, pleated skirt, and exquisite jewelled neckline. Teamed with simple black courts and a sophisticated updo she looks as proper as her character Blair Waldorf, but with a touch of Hollywood dazzle!
