It was a 3-way tie for Best Dressed this week, which is very rare.

You guys couldn’t pick a clear winner between Gwyneth Paltrow in her stunning Elie Saab Couture gown and Reese Witherspoon in a cute Jason Wu strapless mini dress.

Two different styles, but two great looks.

I opted for Leighton Meester in Herve Leger.

It’s been a long time since Leighton has looked this good and although many didn’t like her footwear choice, I think the dress and her flawless make-up more than made up for it.

Reese Witherspoon attended the “Vital Voices 2010 Global Leadership Awards” last night.

The actress is the Honorary Chairperson of the Avon Foundation who held this event at The Kennedy Center in Washington, DC.

With her hair pulled back Reese wore a cobalt blue Jason Wu ‘Kristie’ mini dress’ with a peplum at the waist.

I love the splattered black beaded details which cascade down the strapless mini which gives the look texture.

Black peep-toes complete the look.

I like that she didn’t add too much bling to this look.

Newly single Reese Witherspoon showed no signs of the ‘break up blues’ as she walked the red carpet at the Saks’ Unforgettable Evening Benefiting EIF’s Women’s Cancer Research Fund at the Beverly Wilshire Four Seasons Hotel last night.

I love the Jason Wu Pre-Fall 2010 dress with a beautiful black lace overlay and black satin belt, but I prefer the length of this dress on the runway.

In saying that I couldn’t see Reese sporting such a short dress, so the dress works very well for her and the length is event appropriate.

What I would’ve liked to have seen was a different hairstyle. It feels like she’s hasn’t changed it since her break up with Ryan Phillippe.

An up do would’ve worked well with this look.

Lengthening the dress. Was that an upgrade or downgrade for Reese?

Isabel Marant is the go-to label for Parisian cool girls, and it looks like Reese Witherspoon is also a fan.

The actress was spotted out and about in Beverly Hills this week wearing an Isabel Marant Fall 2009 tiered short print dress with frayed edges.

The chic dress was mummy-fied with a navy cardigan, but she added a cool pair of aviators and navy wedges to her look.

Net-A-Porter.com will be adding Isabel Marant to it’s already impressive list of designers from February 2010.

We can look forward to drooling online at the designer’s effortlessly hip pieces including boyish trophy jackets, slouchy pants and easy-chic mini dresses.

Lets not forget the studded suede pirate boots Sienna Miller wore last year which shot to #1 on many of our wish lists.

Those of you who got the Zara version were very lucky.

“Friday Night with Jonathan Ross” London

Reese Witherspoon was in London this week to meet MPs at London’s House of Commons to talk about domestic violence issues, as part of her role as honorary chairwoman of the Avon Foundation.

Whilst in London she took time out to visit the “Jonathan Ross Show” which is tape on Thursday but aired on Friday.

Her lace dress could be a modified dress from Stella McCartney’s Resort 2010 collection, which she pairs with bold red lipstick and cute Stella McCartney mesh heels.

She’s glowing here. I just love this look.

“The Young Victoria” Los Angeles Premiere

Emily Blunt wears a short and sassy black and white print flutter sleeved Marchesa dress.

The black ribbon is a nice touch, the tights I can live with but I’m not so crazy about her heels.

“Invictus” LA Premiere

I love the texture of Michelle Monaghan’s silver one-shoulder RM by Roland Mouret dress.

The voluminous hips are flattering rather than disguising, and I love her accessories including her Diego Dolcini heels and statement necklace which really brings this look to life.

BAM Belle Reve Gala With A Performance Of A Streetcar Named Desire, New York

Cate Blanchett opted for a grey strapless Armani Prive dress with a lace overlay, paired with black pumps.

Even without the wow factor, Cate still looks great.

I would kill for those stunning earrings.

19th Annual Beat The Odds Awards, LA

Zoe Saldana plays is safe wearing a navy blue Alaia dress paired with a Alaia belt and black pumps.

This is a tad boring for me.

BBC 2 Gig, London

Immigration clearly didn’t get my memo.

Leona Lewis wearing corsets with everything is just not funny anymore.

The girl needs an intervention.

“In Bloom By Reese Witherspoon” Launch, New York

I was starting to believe L’Wren Scott was only made for Nicole Kidman and Kyra Sedgwick.

Reese Witherspoon has worn a lot of pretty dresses promoting Avon, and this dress continues that trend.

Wearing black pumps the actress wore a pretty hot pink L’Wren Scott black printed dress from the Spring 2010 collection.

It’s the perfect ‘ladies who lunch’ frock.

Cointreau Party, Brazil

Even though Dita von Teese’s Malandrino Fall 2009 metallic dress was presented in silver, the princess of goth of course opted for the black version.

She totally picked the right colour as this gown looks amazing on her.

I love the way it drapes on the hips.

Bruce Hoeksema Cocktail Party, New York

Gwyneth Paltrow is the first celebrity to wear a dress from the recently presented RM by Roland Mouret Spring 2010 collection.

She paired her navy and gold tiger print belted dress with a paired of the Christian Louboutin for Roland Mouret heels as shown on the runway.

As always she looks fabulous to me.  I know a few of you are very much over her.

Jimmy Choo Project Pep Launch Party, London

Tamara Mellon wouldn’t be caught out without her own accessories.

For the “Jimmy Choo Project Pep Launch” at Selfridges she modeled a Jimmy Choo Char Clutch and Jimmy Choo Pep Loop sandals, whilst looking stunning wearing a red Valentino dress accented with a bow on one side.

1st Annual Guggenheim Art Awards, New York

Kylie Minogue wore a nude coloured Calvin Klein Spring 2010 dress which looked stunning against her warm complexion.

Loving the soft make-up and matching accessories.

Julianne Moore appears to be a big fan of this Calvin Klein collection, as she has worn many pieces recently.

This time she opts for a simplistic grey dress, paired with black tights, black heels and a black clutch.

Switches On The Harrods Christmas Lights, London

Dannii Minogue has an J’Aton Couture obsession because she wore two dress by the design duo last weekend, and last night she donned another one of their creations to switch on the Harrods lights.

She looks so cute. I love the ruffled detail on the shoulder.

Music Unites Fall Masquerade Gala, New York

White was the colour of the night as Kerry Washington graced this event with her flawless beauty wearing a very girly Marchesa satin strapless dress with a structured tulle overlay and embroidered empire waist.

Her sassy dress was paired with a Marchesa clutch with a crystral clasp, which complemented her black peep-toes with a diamanté embellishment.

Georgina Chapman also opted for a white Marchesa dress, but her was completely made out of feathers.

The designer also wore a ring from her recently launch Garrard collection.

Reese Witherspoon is the current face of Avon, and that gorgeous face looked very stylish wearing a Narciso Rodriguez Spring 2010 strapless dress with a white bodice and a black sheer skirt overlay.

I’m glad the dress is not squishing her twins like it does on the runway model.

I think you know that style-wise I find Lauren Conrad very frustrating, but not on this occasion as she was easily one of the best dressed on this red carpet.

I love that she wore a modern Herve Leger bandage dress whilst sporting vintage marcel waves.

Her look was paired with bright red lips with matching nails which gets me thinking someone has been taking some style tips from Dita von Teese.

Trib Two’s as standard.

Fergie looked pretty fab in her nude feathered Valentino dress.

It’s always a snooze-fest whenever Courteney Cox walks the red carpet, and this occasion is not different.
