Sonia Braga's New Flick... Derek Lam Gives Power to the People...

ONE TIME ONLY: Brazilian babe Sonia Braga is going from her guest stint on ABC’s “Brothers & Sisters” — “Thank God I got to kiss a boy” — to playing a flamenco dancer in Katherine Griffin’s film “Butterflies & Lightning.” “The movie’s about love and family and people going away and coming back,” explained Braga, spotted at Narciso Rodriguez’s show. “It’s not physical, but spiritual.” (She means it’s a fantasy, with a fairy-tale hook.) As for her plans for fashion week, Rodriguez was it. “What brings me here is my love for him,” she gushed.

PEOPLE’S CHOICE: Derek Lam is giving the power to the people. The designer unveiled his first crowdsourced collection, done in collaboration with eBay, on Wednesday morning at Lincoln Center’s Alice Tully Hall. Sixteen looks were shown, with each revolving around iconic dress silhouettes — from a simple shift and denim shirtdress (the latter with a kicky peplum in the back) to boho printed frocks and cotton poplin evening gowns, priced from $125 to $295. Come May, however, only five pieces will make it to eBay’s virtual sales floor, depending on which ones rack up the most online votes.

“I want this to be fun and interactive and do something out of the box,” said Lam, nudging editors to cast their ballots on the computer screens nearby. Votes can be placed on Dereklam.ebay.com (which will continually update the dress rankings) until Feb. 28. Results will be revealed on March 1.

NANETTE’S CROWD: A group of Nanette Lepore’s friends, including Natalie Morales, Patricia Clarkson, Kelly Rutherford, John Slattery, Kelly Macdonald and Lili Taylor, came out to support the designer at her show Wednesday morning. Clarkson said this was her only show this week. “I know her [Nanette]. I’ve worn her clothes, and I have a few occasions coming up,” said the actress. Asked about her latest projects, she replied: “I’m not working by choice. I’m taking a break and waiting for something to float my boat.”

Morales of “Today” said she’s looking forward to covering the Royal Wedding on April 29. Meantime, Slattery said his new movie, “The Adjustment Bureau,” in which he plays “an angel of fate,” will be out next month. He also just filmed an independent feature, “Return,” which should be released next year.

GAGA FOR THE IPAD: With its first iPad app, which launched today, Vogue magazine is trying something a little different. Rather than containing the entire issue, the app, called Vogue Cover Exclusive, will hone in on the cover celebrity and feature exclusive content to accompany the cover feature. For the launch March edition, it centers around cover girl Lady Gaga, featuring a never-before-seen interview with her, video segments from the shoots, and an audio diary of Gaga on tour. The March launch is sponsored by MAC Cosmetics. The app costs 99 cents. “With the Cover Exclusive app, we have created a custom brand of journalism targeted at the Twitter generation — a digitally enhanced version of our cover story, with exclusive video, audio and photographic outtakes,” Vogue editor in chief Anna Wintour said.

SCANTILY CLAD: Waris Ahluwalia managed to draw a crowd for his first presentation, at the Museum of Art and Design. Whether that was a result of his scantily clad models (in just underwear and a House of Waris scarf) or Ahluwalia’s design cred remains to be seen.

Chloë Sevigny showed up and said her favorite part of fashion week was “seeing what my friends create, and celebrating my friends, enjoying what they do.” So far as Ahluwalia is concerned, Sevigny said his first presentation was imperative for the education of a larger fashion crowd. “They know Waris, they’ve seen him around forever, but have never really seen his work, so it’s a great thing for him to finally have a presentation during fashion week when everybody’s here and everybody can celebrate him,” she said.

Sevigny is taking time off, having just wrapped six months of filming “Big Love.” “I’m taking a little time, working on a collection for Opening Ceremony, I have something in development at HBO, and I’m auditioning and reading scripts, but I don’t have anything lined up,” she said, adding that the aesthetic for her new collection would be “leather and lace.”

Designer Tara Subkoff had tentatively planned to do a collaboration with Ahluwalia, which was nixed at the last minute due to time constraints.
