Earlier this month, Glee creator Ryan Murphy revealed that Sarah Jessica Parker would guest star on season four of the series playing the editor of Vogue.com--and that Anna Wintour would take care of the costumes. (Remember that Wintour's daughter Bee Shaffer works for Murphy's production company, so... family connections.)
And earlier today, Murphy tweeted the first photo of SJP on set as Isabelle, Kurt's boss at Vogue.com (got to brand the digital side too!!). Looks like she's wearing a Lanvin necklace, and who can ID the rest? we've figured the rest out!
Update: I'm pretty sure SJP's dress is by up-and-coming label Faster Than Paris. The label, founded by Tracy L. Cox, a stylist who used to work for Patricia Field at SATC and Troy Arnold, who has worked for Peter Som and DKNY, is featured in the View section of Vogue's September issue. They're photographed with Chanel Iman who we're pretty sure is wearing this exact dress. Also, Parker is quoted in the story: "That wonderful Tartan shift dress is one of the greatest pieces I've seen in five years." --Dhani
Update # 2: She's also wearing a Delfina Delettrez detaille necklace as a bracelet.
Looks like AW's doing a nice job as costume designer so far.
