In An Education, set in early-‘60s Britain, Carey Mulligan plays a straitlaced schoolgirl whose studious routine is upended when she meets debonair thirty-something David. At the film’s L.A. premiere, the winsome actress eschewed her character’s shoulder-grazing locks and gray wool uniform for a chic pixie cut and a Lanvin frock that featured a sophisticated floral print rendered in an autumn palette.

Whip It, Drew Barrymore’s foray into feature filmmaking, stars Juno’s Ellen Page as a Texas teen who longs to ditch her small-town beauty-pageant career for the thrills of female roller derbies. At the premiere, Barrymore turned heads in a black sheath dress by L’Wren Scott and red peep-toe platforms by Casadei.

There were plenty of noteworthy looks at Burberry Prorsum’s much-anticipated spring 2010 show during London Fashion Week, particularly ELLE October cover girl Victoria Beckham’s black cocktail frock from her own line. Attendees also included Liv Tyler, Gwyneth Paltrow, and Emma Watson.

The young stars of Kevin Tancharoen’s Fame remake stepped out for its Hollywood premiere last night. So You Think You Can Dance alum Kherington Payne dazzled in an asymmetrical metallic number, which she paired with Stuart Weitzman’s black satin Tijuana platforms. Last week we watched Payne and costar Kay Panabaker preview makeup looks for the premiere.

Dior Beauty hosted a fête for the tenth anniversary of J’Adore at NYC’s Standard Hotel this week. Attendees included Coco Rocha, Lydia Hearst, Theodora Richards, Lykke Li, and Olivia Palermo, who was downtown chic in a silver-metallic dress, studded jacket, and lace-up ankle boots.

January Jones was among the stars who turned out for Tommy Hilfiger’s spring 2010 show last night. The shocking-pink hue of the actress’s dress (by Hilfiger) was a stark contrast from the cool color palette of her Mad Men character, Betty Draper.

In Love Happens, Aaron Eckhart plays a widower turned best-selling self-help author who subsequently becomes romantically involved with one of his seminars’ attendees, played by Jennifer Aniston (who recently spoke with ELLE about relationships). Aniston certainly didn’t need any sartorial help at the movie's Hollywood premiere: The actress wore a gorgeous silver beaded minidress by Valentino.

Spanish designer Davidelfin presented at Bryant Park for the first time last Thursday, garnering acclaim for his spring 2010 collection’s powerful blue-and-green palette. R&B songstress Amerie was so taken with the show that she requested this caped aqua minidress, which she wore to Sunday night’s MTV Video Music Awards.

In one of the MTV Video Music Awards’ most unpredictable moments last night, Kanye West interrupted Taylor Swift’s acceptance speech for her Best Female Video win to say that Beyonce’s “Single Ladies” is “one of the greatest videos of all time.” Swift handled the outburst with grace, looking perfectly elegant in a Kaufmanfranco gown adorned with sparkling silver sequins.

In Pedro Almodóvar’s Broken Embraces, Penélope Cruz plays a struggling actress who makes a living as a secretary and call girl. As her Best Supporting Actress Oscar (for Vicky Cristina Barcelona) proves, acting is hardly a struggle for Cruz. And neither is fashion: The Spanish-born star looked lovely in an aqua cocktail dress by RM by Roland Mouret at the movie’s Toronto Film Festival premiere.
