Kim and Kourtney Kardashian are taking New York, and looking great doing it. Have you ever wondered how their make-up always looks so flawless? Well, being able to afford your own make-up artist doesn't hurt. But there are other secrets, too. Lucky for us, the girls' New York City make-up artist Troy Surratt revealed some of them to UsMagazine.com:

1. Make friends with foundation. Many girls avoid foundation because they think it looks fake, says Surratt, but the right formula and technique will give your skin a flawless appearance. First, apply a lightweight gel-cream base like Dior DiorSkin Nude Natural Glow Crème-Gel ($48, sephora.com) with a foundation brush. Then, pat it into your skin with a makeup sponge.

2. Warm up your skin. When applying bronzer, create a triangle shape by blending it around your hairline (at the temples), on your cheekbones and down to your chin. "This draws all of the light to the center of your face," says Surratt who recommends Shiseido Oil-Free Bronzer ($35, nordstrom.com).

3. Enhance your bone structure. Smile and add a pop of pink blush to the fullest area of your cheek. Then, dab a shimmery highlighter over the blush as well as on your cheekbones to make them look more prominent. Surratt uses Dolce & Gabanna The Blush Luminous Cheek Colour in Provocative ($44, saksfifthavenue.com) with Mally Beauty in Life is Lighter ($40, mallybeauty.com).
