When you get to interview world-famous beauty experts every day for a week straight, you pick a few things up.

Products are named after Marc Jacobs's tattoos.

Bonjour belles! We’ve descended on the City of Lights to take in the sights, and of course that includes gorgeous beauty looks coming down the catwalk. From the berry lips at Anthony Vaccarello to the bleached blondes at Haider Ackermann, click through to see what’s been big in backstage beauty here in France this week.

Yesterday was a day of beautiful, impeccable hair and makeup. Proenza Schouler's girl was a bit dirty and downtown (as she usually is), Marchesa's was regal (ditto), and Anna Sui's was, well, you'll just have to see for yourself! Click through for all the hair and makeup looks from Proenza, Marchesa, Rachel Zoe, and Anna Sui.

We spent our Sunday worshipping at the church of fashion--we dragged our sorry selves out of bed really early to check out Victoria Beckham's look at the New York Public Library and lasted all the way until the evening, when we ooh'ed and ah'ed over Zac Posen's signature elegant beauty look. (Start practicing a gorgeous bordeaux lip!)

Yesterday was pretty exciting, fashion-wise: Alexander Wang, Prabal Gurung, and Altuzarra all showed collections, and we were lucky enough to be backstage with the beauty teams, too. Click through to check out the cognac ponytails at Wang, a super dramatic eye at Monique Lhuillier, the coolest teenagers ever at Chloe Sevigny for Opening Ceremony and tons more.

We're spending the week skulking around backstage at some of the hottest (and coolest) shows at New York fashion week to bring you the best beauty looks, new products, and gossipy tidbits that we pick up in our travels. So click through to check out the beauty backstage at Jason Wu, Rag and Bone, Rebecca Minkoff and tons more.
