Always, the dressing and makeup of a famous star tend to cause a sensation of fashion trend among the public. Here, let’s learn something about the celebrity styles and the fashion trends.

1 Red Carpet Buzz: Mary-Kate Olsen

David Fincher’s Holly Rollers, which stars Jesse Eisenberg as a Hasidic Brooklyn teen who begins smuggling drugs, premiered at Landmark’s Sunshine Cinema last night. Mary-Kate Olsen, whose sister’s beau Justin Bartha appears in the film, looked wildly chic in a leopard-print top, harem pants, and fringed clutch.

2 Red Carpet Buzz: Gemma Arterton

Prince of Persia: The Sands of Time, Disney’s latest fantasy film, brings the 2003 video game of the same name to the big screen with Jake Gyllenhaal in the title role. At its world premiere in London, star Gemma Arterton wore a princess-like tulle Valentino gown, which she complemented with a bold red lip.

3 Red Carpet Buzz: Kate Bosworth

On May 6 in Beverly Hills, New York social chronicler Derek Blasberg celebrated the launch of his new book, Classy, which advises on how to be a true lady. Kate Bosworth, one lady who needs no such advice, looked perfectly polished in a flattering Missoni minidress.

4 Red Carpet Buzz: Leighton Meester

Leighton Meester celebrated her new role as Herbal Essences’ Global Ambassador in Madrid yesterday. The Gossip Girl beauty’s perfect coif was the event’s mane attraction, but she also earned style points for her gorgeous white Hervé Léger by Max Azria dress, which she paired with gold Pierre Hardy sandals.

5 Red Carpet Buzz: Kristin Davis

With the premiere of Sex and the City 2 only a few weeks away, half of the fabulous foursome stepped out for the White House Correspondents’ Dinner Saturday night. Cynthia Nixon wore a gray Calvin Klein gown, and Kristin Davis went for high glamour in a floor-sweeping cream-colored vintage Balmain dress, which she paired with a gold Judith Leiber clutch.

6 Red Carpet Buzz: Sarah Jessica Parker

On April 29, the night’s New York City Ballet spring gala, Sarah Jessica Parker looked like a dancing queen in an embellished blush Elie Saab cocktail dress, which she paired with an emerald L’Wren Scott jacket. And might we note that it’s now less than a month before our favorite small-screen fashion icon returns to the big screen?

7 Red Carpet Buzz: Gwyneth Paltrow

Benefit for Bent on Learning on April 28, an organization that provides free instruction in yoga and meditation to NYC public school students, drew appearances from the likes of Madonna and Gwyneth Paltrow. And Paltrow’s curve-hugging metallic Victoria Beckham minidress was the perfect choice to show off an enviable yoga physique. We also loved her tousled strands in Iron Man 2.

8 Red Carpet Buzz: Carrie Underwood

At the Academy of Country Music Awards on April 18th, Carrie Underwood became the first woman to take the entertainer of the year award twice, and picked up a Triple Crown trophy as well. The American Idol alum celebrated her big win in a plunging full-skirted Rafael Cennamo minidress, which she paired with silver, crystal-T-strap platforms by Stuart Weitzman.
