Dianna Agron and Other Best Dressed Celebs of the Week

Dianna Agron The Late Show with David Letterman New York City Aug 2011

Many celebs dressed up this week and got into publicity mode making the rounds at premieres, network events, and talk shows. From a big screen concert experience, courtesy of the cast of a popular TV show, to a buddy comedy where the buddies swap bodies, there were certainly plenty of projects to go out and promote. Even Mila Kunis and Justin Timberlake were still pounding the pavement for Friends with Benefits as the duo headed overseas. This heavy push may translate into bigger audiences, but it's also a great opportunity for some fashionable stargazing.

Glee star Dianna Agron stopped by the Ed Sullivan Theater in New York City for an appearance on the Late Show with David Letterman to promote Glee: The 3D Concert Movie. Her black velvet Stella McCartney Fall 2011 peplum number was a great choice for the notoriously chilly theater. Yves Saint Laurent pumps rounded out the ensemble. Hart of Dixie star Rachel Bilson once again demonstrated how effortlessly style comes to her as she donned a sophisticated Erdem Resort 2012 outfit to the CBS, The CW and Showtime TCA Party. The floral patterned blouse and red tapered pants were further set off by those leopard Christian Louboutin pumps and black Giuseppe Zanotti clutch.

Still busy promoting her latest film, Mila Kunis went over to the BBC Radio 1 studios in London. Even though she arrived in a playful Oscar de la Renta Resort 2012 polka dot dress, she decided to change into a long-sleeved navy Cacharel Fall 2011 mini partially covered with a floral print. Those Elie Saab t-strap cream pumps are from the designer's Fall 2011 offering and the quick-change artist also sported Ray-Ban aviators as well as the same blue Chanel quilted clutch she carried earlier. Alexa Vega has certainly grown up since the first Spy Kids flick. The young actress looked lovely and age-appropriate in a pale pink Keepsake sleeveless dress partnered with Yves Saint Laurent nude heels and a flashy clutch at the Los Angeles premiere of the latest edition to the franchise, Spy Kids: All the Time in the World in 4D.

Leslie Mann showed up to the Los Angeles premiere of The Change-Up in a white dress from the Marchesa Resort 2012 collection. The sculpted shoulders featured gold embellishments which complemented her gold Marchesa envelope clutch. Maybe there should just be a reserved space on this list for Olivia Wilde whenever she has a project out because she almost always brings her “A” game to the red carpet. She also attended The Change-Up's Los Angeles premiere, where the film and TV star rocked a red Antonio Berardi Pre-Fall 2011 wool-crepe frock with exaggerated shoulders. A pair of equally hot satin Maniac heels by Brian Atwood along with a Kara Ackerman Designs bangle and Wilfredo Rosado earrings polished off the on-fire look.

Amber also had on Brian Atwood Marcella pumps featuring a gold pin heel, a Kara Ackerman Designs ring and earrings by Dana Rebecca Designs. Freida Pinto demonstrated how to perfectly accessorize a white dress when she made an appearance on the Today Show to talk about her film, Rise of the Planet of the Apes. Her Calvin Klein selection is actually a shortened version of a dress from the label’s Pre-Fall 2011 collection which also featured a square neckline and exposed zipper. The vivid blue additions in the form of Brian Atwood peep-toes and a Chanel bag elevated the dress from conservative to fashion-forward.

Get ready to go mad for the Banana Republic Mad Men capsule collection. The take-off on the hit AMC series won’t be unveiled until August 11, but Jaime King provided a sneak preview at the Carrera Sunglasses Escape LA event held at the Chateau Marmont. Her lace cap-sleeve dress was combined with unconventional Prada wing-tip platform espadrille oxfords. It’s as if Betty Francis borrowed a pair of shoes from her former husband, Don Draper.

Silky summer separates including a mint skirt and ivory tank were taken up a notch thanks to feather earrings, a skinny tan belt, those Figueroa shades by Elizabeth and James as well as a Paraty red bag and ankle strap flats both by Chloé.
