This week, editors, socialites, celebrities and the daughters of celebrities helped define the style of the most fashionable city in the world at Paris Fashion Week.

Alicia Keys maintained her color palette of black and white all week at Givenchy, Stella McCartney, and YSL. The first look is so Melrose Place and I love it.

Stepping out of the box for the Chanel show, Alicia wore head jewelry, which I think could've been cooler if placed over a center part.

Katy Perry is one of those method actors who can't shake their characters that easily after a role—which is apparently what happened with her after The Smurfs.

Fashion Director and Editor-at-large at Vogue Nippon, Anna Dello Russo, is my favorite kooky fashion person.

Anna wore lots of long-haired fake fur this week.

She's simply the coolest. Just when you think she can't get any more La Toya Jackson, she goes and wears a chic, pale pink suit.

Leigh Lezark was partial to pants.

Whenever women—like Li Xiao Lu, here—paste their hair to their heads, it always reminds me of Catherine O'Hara in Beetlejuice.

Jewelry designer Bao Bao Wan's feet are very Seuss-ian.

Princess Sirivannavari Nariratana of Thailand's style grossed me out at first, mostly because of that first look she wore to Christian Dior, but she won me over with the fringed jacket. I think it's really cool and unexpected for a princess to dress like new money.

You don't even need to hear editor of L'Uomo Vogue Giovanna Battaglia speak to know she's European.

The movie stars are never as exciting at these things as the industry people and socialites. From left: Jessica Alba, Salma Hayek, and Tilda Swinton.

Ugh. I thought it was bad enough when Rosario Dawson's dress was all boring and dowdy in the front, but then she turned around to show that the opened-back leopard lace was like a skanky pair of crotchless panties. That's probably redundant. I think all crotchless panties are probably skanky, since that's the point of them.

So many daughters of famous people: Theodora Richards (as in Keith Richards), Jade Jagger (as in Mick Jagger), and Tali Lennox (as in Annie Lenox).

Sonja Kinski (as in Natasha Kinski); Sarah Margaret and Rainey Qualley (as in Andie MacDowell); and Stella Schnabel (as in Julian Schnabel).

You know no one in the Missoni family has ever gone cold, what with all the wool and knits they wear (as seen here on Margherita Missoni). Typically I hate nude hose and open toes, but model Elena Perminova has a Marcia Brady thing going on. Hands down my favorite outfit of the entire week is worn by Ulyana Sergeenko, who is quite clearly in PJs. I'd bet a copy of The Marble Faun on the fact that she's intentionally channeling Edie Beale.
