Ashley Olsen was the lone Olsen twin at last night’s CFDA Awards. While Ashley rocked the red carpet, MK was in Montreal filming Beastly. The glam event was held in New York City and celebrated the best in American fashion. Lots of celebrities were in attendance, including Blake Lively, Kirsten Dunst, Ashley Olsen, Lydia Hearst, Hilary Rhoda, Claire Danes, Rachel Zoe, Coco Rocha and Molly Sims.

Ashley looked superb in a surprising orange dress. The vintage-inspired gown is from Ashley’s own collection, the Row. It’s a bold choice for Ashley, but is very much reminiscent of the Row aesthetic. It has a similar dramatic back to the long white gown Ashley wore to the MET gala last month.

Rodarte, consisting of design duo Kate and Lauren Mulleavy, took home womenswear designer of the year. The sisters topped Narciso Rodriguez and Marc Jacobs for the honors. Scott Sternberg of Band of Outsiders won menswear designer of the year and Marc Jacobs for Louis Vuitton took home the international award.

Olsen favorite Proenza Schouler won accessory designer of the year and Alexander Wang took home the Swarovski award for womenswear.

Mary-Kate Olsen made an appearance at the same red carpet event as Ashley last night - the premiere of The Hangover. The sisters walked the red carpet separately and both showed off their individual style and sunny smiles. Ashley’s boyfriend Justin Bartha stars in the film about a bachelor party gone wrong. Justin plays Doug, the grrom-to-be, who gets lost during the drunken escapades. The next morning, it becomes the groomsmen’s quest to find the lost man before his fiance finds out.

Mary-Kate looked great in a blazer, a TopShop dress, pink Lennon sunglasses and Prada heels. Her hair looks shiny and healthy and I love that both she and Ashley flashed big smiles for the camera. I hope they enjoyed the film!

MK has her own film project in the works now, the independent movie Meskada filming starts in New York in a few days. I’m really excited to see Mary-Kate back on the big screen. Hopefully we’ll hear of more 2009 projects soon!

Ashley Olsen looked crisp, clean and stunning at the premiere of The Hangover last night atHollywood’s Grauman’s Theatre. Ashley made the rare red carpet appearance to support her boyfriend, Justin Bartha, who stars in the film. Ashley didn’t want to steal Justin’s thunder though, so they walked the red carpet separately.

I don’t think anyone in Hollywood does minimalism as well as Ashley is right now. She pairs a simple Calvin Klein dress with snakeskin sandals and no accessories (except her glowing skin and a smile!) and looks fabulous. She’s also debuting the hair cut she got while she texted Marie Claire. I like the shorter ‘do. Do you?

The Hangover is about a bachelor party in Los Vegas gone horribly awry -so awry that the groomsmen lose the groom-to-be. Hilarty ensues. The Hangover has opened to very positive reviews and I’ll admit I’m excited to see it. Justin plays Doug, the missing groom, so who knows how much screen time he’ll get. Regardless, it should be fun. Justin was adorable in the National Treasure films.

Mary-Kate Olsen opted for period glamour as she donned Lacroix at last night’s Costume Institute Gala. The dress, adorned in metallic lace and silver-embroidered bustier-basque, was definitely a bold move and I think MK pulled it off.

This year’s theme was “The Model as Muse: Embodying Fashion”, which celebrated the Metropolitan Museum of Art exhibit of the same name. The exhibit celebrates the role of the model in fashion, as a model, a muse and more. It’s supposed to be spectacular, so if you’re in New York any time soon, be sure to check it out.

MK and Ash opted for very different looks this year. Whose do you like better? Whose would you be more inclined to wear? And why didn’t Nate come?

Ashley Olsen looked positively regal at last night’s Costume Institute Gala. She stepped out in a long white dress that was very demure in the front, but had a sexy and dramatic back. Ashley walked the red carpet with her boyfriend Justin Bartha, who cleaned up nicely in a tuxedo!

Tons of stars came out to celebrate the event and the fashion was spectacular! Pop Sugar did a great job of covering nearly every starlet who stepped out last night, so if you want more coverage, be sure to check it out!

Ashley Olsen was one of several celebrities who came out last night to attend the Cartier 100th Anniversary Party. The party was held at Cartier’s flagship store on Fifth Avenue. Every attendee left with a bright red goodie bag. I wonder what is in them?!

Cartier, a french jeweller founded in 1847, was celebrating its 100th anniversary in America. They want all out with a swanky, star-studded party! I’m disappointed Ashley didn’t walk the red carpet pre-party, but am glad we caught a glimpse of her outfit as she left.

Other attendees included Anne Hathaway, Demi Moore, Eva Mendes, Kate Hudson, Justin Timberlake, Patti Smith, Rachel Weisz and more. All the stars were decked out in their very best - you can see a slideshow here!

Immediately after attending the Tribeca Film Festival Women Filmmakers Brunch on Thursday, Mary-Kate Olsen joined her sister Ashley Olsen for the 16th annual Women of Distinction Luncheon.

The luncheon, which was held at the Waldorf Astoria, honors women who have made a difference in film and television arts. They were founded in 1993 by the Hollywood Chamber of Commerce.

Mary-Kate Olsen did some jury duty yesterday as she presented at the Tribeca Film Festival Awards Night party. Mary-Kate was joined on stage by Debra Messing and the two of them unveiled the winner for the category they judged, Best Narrative Short.

The 2009 winner of Best Narrative Short was The North Road (La route du Nord),, a film by Carlos Chahine from France.

“We ultimately chose the winner for its poetic, truthful and unsentimental portrait of an exile’s return home to deal with his father’s death 20 years earlier,” the jury said in a statement. “The director, Carlos Chahine, portrays the absurdities and contradictions of how we deal with grief through humor, freshness and subtlety.”

MK was very vocal in the press about how honored and pleased she was to be a jury member. I hope she thoroughly enjoyed the experience!

Lots of great films, filmmakers and actors were honored at the ceremony last night. You can see a complete list of winners here. The film festival continues until May 3rd.

Mary-Kate Olsen was one of several celebrities and Tribeca Film Festival jurors who came out this afternoon for the Women’s Filmmaker Brunch. The event, which was held at City Hall in NYC, celebrated women in film and women filmmakers. Other attendees included Debra Messing, Julianna Margulies and Parker Posey.

MK looked great in her leather jacket, black booties and hot pink paneled skirt. I’m loving the bursts of color she’s been wearing recently. She chose purple for the Matthew Williamson for H&M launch party earlier this week. The simple no-fuss makeup and hair cap the look of perfectly.

I love that MK is a Tribeca Film Festival juror! She’s been out and about so much lately. I only wish I could say the same for Ashley. Ash has been laying really low in Los Angeles these past few days

Mary-Kate Olsen looked stunning as she arrived at the party for the Matthew Williamson for H&M launch party. The party was held at The Majesty Yacht Cornucopia which docked at Pier 17 in New York City.

Matthew Williamson designed a capsule collection for H&M, following in the footsteps of other designers like Karl Lagerfeld and Stella McCartney. A smaller, spring collection debuted at H&M stores worldwide on April 21st and sold out in minutes. A larger summer collection will debut on May 14th and it is expected to stay in stores for a longer period of time.

Mary-Kate was wearing a belt from the Summer Collection, pairing it with a striking purple blazer and a body conscious one-shouldered dress. I love the look! MK has been making some daring style choices for the red carpet lately and it’s really paying off.

Other celebs in attendence were Alexis Bledel, Helena Christensen, Daria Werbowy and more. All were rocking pieces from the collection.

I don’t have access to these images, but MK was seen out and about in New York yesterday and Ashley was spotted at the LAX airport! See the images here.
