How do you get a bunch of celebrities to model your clothes, have their pictures splashed across a myriad of blogs, newspapers and magazines, all for FREE? Without signing any of them to a multi-million dollar contract.

Easy!

You invite them to celebrate Chanel's Bijoux de Diamonts, the 80th anniversary of, then tell them they can wear whatever they please from this year's collections.

I mean, who wouldn't go?

Blake Lively went for a bit of old Hollywood glamour in a silver halterneck dress with blush panelling. LUSH. Want those shoes.

Diane Kruger wins again in a blue/black shiny tile-effect dress. J'adore this, especially with the touch of yellow.

Polished perfection for Leigh Lezark who chose a camelia patterned, high neck gown. Oh the fantasy of it all!

Linda Evangelista went for a classic Chanel knitted ensemble. I'm not sure I like all this hair on her, I wish she'd cut it or wear it back, not so voluminous. 

Rose Byrne in a below-the-knee peplum. So elegant, especially with that bag.

Alexa Chun in her signature girlie style. She always manages to find a piece in the collection that sums her style up perfectly.

When there's a lot of Chanel in the room, you can really see the diversity and the absolute refinement it brings, can't you? Love this black and white ensemble on January Jones. So chic.
