For the preview of the Jason Wu Spring 2010 collection many of Hollywood’s hot young things attended.

Who needs fit models when you have beautiful actresses to show off your collection.

Diane Kruger did a complete 180 from her Narciso Rodriguez look yesterday, as she looks sensational wearing a one-shoulder green and black polka dotted Jason Wu Spring 2010 dress with an asymmetrical hem and crystallized Swarovski elements.

From her hair to the tips of her pedicured feet she is total perfection.

Her dress was accessorized with Roger Vivier heels, a Hunting Season clutch and Eddie Borgo and Tom Binns bracelets.

Jessica Stroup gets back to her best wearing a cute Jason Wu Spring 2010 ensemble including a navy colour block skirt and an ivory pintucked blouse with flutter sleeves.

I love the Sergio Rossi red clutch she carried with her look, and her Sergio Rossi’s purple metallic pumps.

My ‘It’ girl Katie Cassidy was in attendance confirming her style-status.

I much prefer the navy skirt she wore with the cream and grey pattern Jason Wu Spring 2010 look which was paired with Sergio Rossi pumps.

Fabulous as always, and sparkling with Miriam Haskell jewelery.

Despite the few times she has worked as an actress Lily Collins still manages to get invited to these major events.

The teen star wore beautiful Jason Wu Spring 2010 aqua dress with a bubble skirt.

This is a great look and I especially love the red waist belt and the patterned bodice.

What I didn’t like were the Sergio Rossi ankle boots.

Seriously, please can we ditch these ankle boots with everything.

I love Amber Heard’s Spring 2010 look, but I just wish she had worn the gold striped runway sweater which also sparkles with Swarovski elements.

Her look is paired with Miriam Haskell jewelery and navy satin Sergio Rossi slingbacks.

Katie Cassidy was the only one who really impressed me at this event.

Jessica Stroup’s ‘Best Red Carpet Newcomber of 2009′ title is being strongly contested by this girl.

Katie was by far the best dress of the night wearing a watermelon Paule Ka Spring 2009 skirt with tulip bubble details, which she paired with a purple bustier trimmed with lace.

As always the pumps don’t really work for me, but everything else - including her Louis Vuitton Motard satin clutch - is perfection.

Noot Seear opted for an edgier/laidback look wearing a Phi Fall 2009 leather skirt with an asymmetrical exposed zipper and a white tank.

I really dislike the shoes with this look.

Editor-in-chief of Teen Vogue Amy Astley, arrived at this D&G sponsored party wearing a grape D&G Fall 2009 top with voluminous sleeves, paired with navy pants.

Kelly Osbourne’s D&G black satin dress was covered with black and white shamrock appliqués on the sleeves to make the dress more interesting.

“Dancing With the Stars” is paying off. She looks amazing.

Victoria Justice looks so grown up, but not too old in her poppy red BCBG Max Azria sleeveless shift dress.

The dress is covered with hundreds of red paillette’s which matches her ruby lips.

Naturi Naughton didn’t go all out this time.

Instead wearing a simple one-shouldered jersey dress, but add a bit of drama to her look opting for a large jeweled belt.

Chelsea Staub’s canary yellow dress would have stood out on the red carpet.

I love the gold detailed neckline on her BCBG Max Azria dress.

I love Miranda Cosgrove’s floaty ribbon print D&G dress.

It’s nice, but not too cutesy.

It very much suits her style and personality.

I feel a bit disappointed by AnnaLynne McCord’s look.

I expected her to be in the same league as Katie, but I’m really unimpressed by this look.

Jessica Lowndes wore a cute strapless dress with a sequined bodice plus a black and white skirt.

I feel like I see this look on Jessica quite a bit.  I love her to try something new.

Lily Collins opted for a black D&G strapless dress.

Selena Gomez wore a silky black and grey ensemble.

Ashley Tisdale wore a Kate Moss for Topshop Trophy studded dress, which draped low enough to expose her bra through the sheer part of the dress.

Her dress was paired with Christian Louboutin snake skin heels.

Jesscia Stroup opted for a black BCBG Max Azria jumpsuit paired with a green clutch and black open-toe booties.

British actress Emily Mortimer was a guest at one of the many Topshop/Topman launch dinner parties, held around the time of the New York store opening back in March.

She wore a black Topshop gold and lace detailed dress, with tights, black heels and a lipstick pink boyfriend blazer.

Lily Collins wore the same dress to “The Serpentine Gallery’s Summer Party” last month in London, with Topshop black and gold sandals and a black clutch.

The blazer was a welcome pop of colour to her all black ensemble, so Emily wins for me.

This dress is available to purchase from Topshop for £65/$135.

Thandie Newton gets another gold star this time for wearing this multi-coloured Matthew Williamson Resort 2010 dress.

Her look is almost a head-to-toe carbon copy of the runway look, but Thandie opted for a skinny gold studded belt instead of the wider runway belt, and she has a smaller bejeweled clutch.

Nude cut-away ankle boots complete this stunning look.

Best Dressed of the Week is going to be very crowded with Thandie and Emma’s looks.

Roisin Murphy finally does one of the silk voluminous shoulder pieces from the Dolce & Gabbana Spring 2009 collection justice.

I’m quite surprised her look is so close to the runway version, as she usually mixes things up a bit.

Her many accessories included bejeweled belt, gold necklace and large copper sequined bag which she carried as a clutch.

My only disappointment are those black patent heels.  Too stale for this kind of look.

Little Boots arrived wearing the same D&G silk brocade jacket with leggings, which Emma Watson wore in her editorial for Elle UK.

Little Boots is quiet daring with her style choices, so I’m surprised she didn’t copy the runway look.

After her disappointing looks at Haute Couture Fashion Week, Dasha Zhukova gets back to her stunning best wearing a cream Azzedine Alaia dress with a frou-frou skirt and a matching waist belt.

Her dress is gorgeous which she complements with a black and white print cropped jacket and Azzedine Alaia shell decorated heels.

After giving birth to her first child a few months ago Tess Daly has already snapped back to her perfect best.

The TV presenter showed off her stunning pins in this gold See by Chloé mini dress with a tiered bodice, which was folded in the skirt to add subtle volume.

Tess accessorized with some very sexy Jimmy Choo Billie Lizard-print sandals and mirrored clutch.

Meg Matthews continues to channel a very demure look. The wild rock chick seems to be a thing of the past.

Meg is wearing the black version of the same Antonio Berardi tweed crew neck dress she wore to the “Harry Potter And The Half-Blood Prince” UK Premiere.

Poppy Delevigne looks super sexy wearing a long sleeved black embellished mini dress with a pair of Topshop frill sandals.

Lily Collins has walked many red carpets, but I’m still yet to see her do anything noteworthy.

Phil Collins’ daughter is supposed to be an actress but I couldn’t name a single film or TV show she has been in.

Lily wore a lace Topshop lace bodycon dress with some Topshop black and gold sandals which very much look like Louis Vuitton Spicy sandals.

Gold jewelery and a black patent clutch completed the look.

Erin O’Connor wore a plunging jade-green Donna Karan Grecian style dress.

The shapeless dress should drown Erin’s slender frame, but the drapes and her elegant stature prevent that.

Natalie Imbruglia red gown is gorgeous but the Chanel black and white bag is so heavy it feels like a slap in the face.

A black clutch would have been much more subtle.

Olivia Palmero wore a champagne coloured dress with a dazzlingly Zara clutch, Topshop leather disc jacket, and Topshop velcro strapped heels.

Either these girls love Topshop as much as I do, or the retailer sponsored this event.

She kept her look simple with scraped-back hair, thick tights, and minimal jewelery.

Kristen Stewart also wore this dress, with bare legs, when she arrived to promote her new movie Adventureland.

It was great to see Kristen’s hair under control, but I feel Lily pulls off this look with more grace, as Kristen posture was so awkward, so Lily wins for me.

Dita von Teese - as we expect - looked spectacular wearing a long draped flesh silk chiffon Christian Lacroix Fall 2008 Couture gown with a pink ombre train, a matching clutch and a copper bow.

The gown has been modified for the better from the runway version.

Lucy Liu is one of my Top 10 Best Dressed actresses on the red carpet. She looks outstanding wearing this white Giambattista Valli Fall 2008 sheath dress, with a woollen cape.

She completed her look with beige Jimmy Choo platform heels, and a taupe clutch.

If this dress looks a little familiar to you, that’s because Victoria Beckham wore something similar by the same designer last year.

I’m so loving seeing Elie Saab on the red carpet so often lately, and I hope we get to see more tomorrow.

Marcia Cross arrived at this event looking sensational wearing a lilac Elie Saab Spring 2009 Couture gown, which sparkled with many embellishments. The gown had cap sleeves and a gorgeous floral detail on the empire waist.

She completed her look with a complementary silver Daniel Swarovski clutch.

Christina Ricci LBD from the Monique Lhuillier Fall 2009 collection had a asymmetrical ruffled detailing, which did not over power her, nor the dress.

Her look was complete with tan Christian Louboutin pumps, and black satin clutch.

Her blunt bangs and red lips just perfect this look for me.

I’m so surprised Emily Blunt picked this dress, because I don’t think it flatters her at all.

My main problem is the pleated bodice and the jeweled detail on the waist.

Eva Longoria always wears bright vivid colours, so this chocolate brown Reem Acra dress is a surprise.

I hope to see a return to bright colours soon.

Like I said last time, Sienna Miller has lost her appeal. Nothing feels fresh or new with her anymore.

Starting with that hairstyle. Haven’t we seen that look a million times before?

I really dislike the colour, and the material of her Ungaro gown also.

Carice Van Houten wore a black and white graphic print Jay Godfrey halter-neck maxi dress.

I’m not quite sure what has happened to Reese Witherspoon.

After her split with Ryan Philippe she wowed us time after time on the red carpet. Lately I always feel so underwhelmed by her choices.

This Dior LBD is cute enough, but she just lacked pizazz.

Lily Collins teal column gown, had a embellished detail on the empire waist, but it failed to impress me.
