>> After reports yesterday, Halston confirmed that a deal with Sarah Jessica Parker has been signed. She's not expected to be involved in Marios Schwab's upcoming designer line for the brand, but will rather be focusing on an active design role — perhaps even as creative director — in Halston Heritage, the brand's contemporary label.

Paper's Mickey Boardman reports of the agreement:

A source at Halston tells us that SJP will actually be a member of the company's board and will receive equity in the company.  Company insiders insist all designing will be handled by creative director Marios Schwab and shudder at comparisons to the House of Ungaro which has suffered ridicule for it's affiliation with actress Lindsay Lohan.

>> Tom Ford Casts A Single Man Star for Spring 2010 Eyewear Campaign —Tom Ford definitely has his favorites — he gave his perpetual campaign model Jon Kortajarena a role in A Single Man, and now he's switched gears and cast one of the film's stars, Nicholas Hoult, in his Spring 2010 eyewear campaign.  Hoult joins Carolyn Murphy in front of Ford's lens.

>> Dree Hemingway scored three top campaigns for the Spring 2010 season — Gianfranco Ferre, Valentino, and Jean Paul Gaultier (styled by Carine Roitfeld), natch.  But perhaps less known is that for every one of those only-girl campaigns, she also wrapped three small film parts last year.

Her acting portfolio now includes a bit part in My Suicide, a "teen coming-of-age romantic dramedy about a media-obsessed geek and the most beautiful and twisted girl in school," in which she plays "Christian Girl #2." The movie, out in the United States Feb. 1, features mom Mariel Hemingway in one of the main roles.  She also plays "School Girl #1" in Privileged, starring Twilight's Nikki Reed.  Her largest role, as "Kristi," comes in The Truth About Angels, about "an ordinary guy [who] escapes his turbulent home life when he is invited to an exclusive Hollywood party by his movie star friend, only to discover that there's more to the glamorous world than meets the eye."

>> Cathy Horyn to Weigh In on Twitter During Upcoming Fashion Weeks —Suzy Menkes may carry her laptop around through Fashion Month, tapping out timely reviews from the front rows, but she has yet to transmit her thoughts via Twitter. The same can no longer be said about Cathy Horyn, who in addition to her usual blogging and reviewing will be joining the Twitter brigrade. T's Horacio Silva announces: "In news that should send shivers down the backs of designers: Cathy Horyn is finally going to start tweeting this season." [@themoment]

>> Erin Wasson never has a problem finding something to say — she recently told the Independent UK of her day job: "I've always been a girl with a massive opinion. I want to be in the know. Your typical model maybe shows up and is happy to be manipulated and is happy to ask no questions, and I'm quite the opposite. I'm really particular about wanting to know the essence and spirit of a situation that I'm in."

Perhaps that particularity and distinct point of view is part of what lead her to start designing in collaboration with RVCA.  Last season, she went big, showing the collection at New York Fashion Week's Bryant Park Tents, but for Fall 2010, it sounds like she's going for an off-site location.  Style.com reports: "We hear Erin Wasson is trading in the Tents for Fall '10 in favor of an ethnic-rug catwalk at ABC Home. Still planning live band though.."

>> Changes at Vogue: More Subway Riding, Less Jane Herman —Yesterday, the New York Post reported that senior Vogue employees are being told that they have to trade in their Town Cars and cabs in for subway rides, but that's not the only adjustment staffers are having to make.  Word is fashion writer Jane Herman, daughter of Fred Segal owner Ron Herman, left Vogue after the New Year for Gap, where she's joining Patrick Robinson in his quest to make Gap cool again, according to a source.

Daisy Lowe is the latest guest designer for Swarovski Crystallized, and her new collection consists of three youthful looks—a necklace, bracelet, and earrings—which Lowe says are "about the earth, moon, and planetary movements." Deep thoughts aside, the we can't argue with the cute factor of these pieces, which are quite the opposite of recent Crystallized collaborations with Jean Paul Gaultier, Philip Crangi, and Jonathan Saunders.
