Last year we saw Demi Moore wearing this Chanel Spring 2010 cute mini tulle dress on the set of her Harper’s Bazaar shoot, but it’s Rachel Bilson who’s brought it to the red carpet.

The actress looks cute enough wearing this baby-doll dress, but both the hair and make-up look the exact the same as the daily candids of her collecting her dry cleaning and shopping around Hollywood.

Shout if you think this is a BDOTW contender, because I think there’s been far better candidates.

Olivia Wilde wore an Alberta Ferretti Spring 2010 dress which had been lengthen from the runway.

I think – know – she should could have pulled of the shorter version with her gorgeous legs, so part of me feels tad disappointed.

I love the dress itself with the contrasting colours and textures.

It’s very event appropriate.

Her look was completed wearing a pair of Jimmy Choo Nova sandals from the 24/7 collection and a matching snake-skin clutch.

Ashley Greene – I believe – is the first celeb to wear a Pre-Fall 2010 look on the red carpet, which only prove how much being taken seriously in the fashion world.

The Twilight star wore a pale lemon J.Mendel Pre-Fall 2010 dress with a sheer yoke, pleated bodice and a draped detail cascading from the waist.

I love the dress and the colour is divine on her, but I really dislike the matchy matchy colour of the clutch and earrings.

Champagne peep-toes complete the look.

I adore Jenna Dewan’s Paule Ka Spring 2009 sweetheart strapless dress with blush brush stroke details.

I love the volume on the runway picture, which also shows us that the dress has a solid black back panel.

The matchy matchy nature of her heels works better for me than it did on Ashley.

Lisa Edelstein pops up every now and then on the red carpet, and every now and then I say wow.

This is one of those wow moments.

Her Emilio Pucci Resort 2010 dress is exquisite.

The embellished details around the empire-waist stop it from looking very “St Tropez”.

Had BDOTW not been so packed should would’ve been in contention.  I might try to squeeze her in.

Lake Bell flashes a rare smile at this event. Maybe she was promised some diamonds *winks*

The gorgeous actress who still looks stunning with minimal make-up arrived wearing a black and white strapless Lyn Devon Fall 2009 belted dress.

Black patent pumps and a white clutch completed the look.

As cute as Dianna Agron looks in her peachy dress. It’s a bit to Disney for my taste.

Her gold criss cross heels are from Bally.
