If you were wondering where all the celebrities were during New York Fashion Week, they weren't just sitting at home. The Berlin Film Festival and a slew of pre-BAFTA events in London yielded some pretty stunning red carpet looks by the likes of Lea Seydoux (in Prada), Lily Collins (in Mary Katrantzou) and Keira Knightley (in Burberry).
Of course, there were some well-heeled NYFW front-row guests deserving of recognition as well, perhaps most notably Alexa Chung, in a chic and practical suit-with-sneakers look at Calvin Klein, not to mention a pastel pink-clad Lupita Nyong'o.
Click through for all that and the rest of the week's best dressed. (And get ready for more -- the BAFTA's are tonight!)
