If you love buying looks right off the runway, the new Marie Claire Backstage Beauty Trends (99 cents on iTunes) is the iPad app for you. From nude smoky eyes to fiery crimson lips, now you can browse the latest beauty trends from fashion week on your iPad. Then choose a model face (in Fair, Medium, Tan, or Deep skin tones) to "try on" all the products to recreate the style. And if you just have to have that bronze eye shadow or ruby lipstick? Marie Claire has partnered with Chanel so you can purchase anything you want. With insider tips and expert application advice from celebrity makeup artist Kate Lee (Keira Knightley is a client), this app is like a guidebook for navigating the new beauty trends. We love that you're able to paint the model faces with your fingertip (just choose one of the many Chanel shades in the Virtual Makeup Tester), so you can unleash your inner makeup artist.
