Fashion highlights: Kanye West wore a Tory Burch tuxedo (it was her menswear debut), fastened together with a gold safety pin. The suit was inspired by one Burch's father Buddy had worn. [Just Jared] Beyonce wore a ravishing, almost prohibitively-tight Pucci number, and got booed with hubby Jay-Z for not posing long enough for pics. [Zap 2 It] Taylor Swift looked all grown-up in a J. Mendel gown. [Coco Perez]  Ashley Olsen's vintage Dior dress was maybe our favorite of the evening. [Just Jared] Tied with Doutzen Kroes in Giambattista Valli and Ginnifer Goodwin in custom Topshop. P.S. What is "custom Topshop"?? [Racked]

We loved spotting little glimpses our buddy/power-publicist Amanda Silverman in the background of all the Just Jared pics!

And in fashion media news, Amazon is launching a flash sale site called Myhabit today, featuring wares by Doo.Ri, Badgley Mischka, Kenneth Jay Lane jewelry, I.Am.Clothing men's wear and BedStu shoes. And Ben Widdicombe has been tapped to edit Unlisted, a new editorial companion to Gilt City. [WWD]
