Lanvin, for the Fierce, Up-All-Night Disco Partybot in You

Paris Fashion Week continues! What did Alber Elbaz cook up for the Spring 2013 collection? Dark heavy metal partybot asymmetrical jumpsuits. Jewel-tone satins. Aggressively square shoulders. Cowboy boots with stiletto heels. Blade Runner-esque raincoats cinched with obi sashes. The makeup was described as being very, very cool. Nothing delicate or frilly here! Both 45-year-old Kristen McMenamy and 20-year-old Karlie Kloss walked in the show, and the overall vibe was: These ladies are not fucking around. Click through for tough cookie realness.

Front row action: Catherine Deneuve, Anna Wintour, Kristin Scott Thomas.
