Stacey Bendet showed off her Alice + Olivia collection for Spring 2010 on Saturday evening in a raw gallery space in the meatpacking district. (How raw? So raw that wooden boards had to be placed over the metal grates on the floors so that a socialite or celeb in 7-inch heels wouldn't be maimed at the show.) The all-female French rock band Plastiscines performed; the crowd included the likes of Lindsay Lohan, Jared Leto, Nicky Hilton, Mena Suvari, Shenae Grimes, Kristin Cavallari, AnnaLynne McCord, and Tinsley Mortimer. Party-hopping reporter Douglas Marshall struck up a conversation with Nylon style director and girl-about-town Dani Stahl, Nylon publisher Jaclynn Jarrett, and Eleanor Ylvisaker, a co-founder of Earnest Sewn and the denim brand's former PR queen.

("Then I could try and get with her brother Mark," Davis writes.) Fourth on the list? Tinsley Mortimer. "Sure, she's my sister-in-law, but we aren't blood relatives." Actually, she's your half-sister-in-law, missy. [Paper]
