Kim Kardashian's Sexiest Style Secrets

What’s her girls’ night out must-have? “Fab Belle Noel jewelry!” says of her just-launched line of baubles with jeweler Pascal Mouawad. Long a fan of eye-catching trimmings, she is living proof that “accessories are everything, and can change a simple outfit!”

“I hate flats!” the petite star says, preferring to lengthen her legs with one of her many pairs of sky-high pumps and boots. She especially loves to sport a “really high pair of heels” on a hot date (perhaps with new beau Kris Humphries?) because “they make me feel sexier!”

Though Kim is always glamorous, when she really needs to pump up the volume she turns to her longtime favorite: “LipFusion lip gloss! I need it!” In fact, Kim loves it so much she was named the face of the brand last year!

You’ll rarely see the star without a belt – and that’s because she loves to play to her strengths. “My favorite feature is my waist!” she says. “It’s the smallest part, so I always wear a belt to cinch it in!”

Kim and her sisters love to share with each other, so it’s no surprise that all three of them swear by the Perfect Skin skincare system. “They’re the only products I use on my face!” Kim gushes of the three-step line.

For such a petite woman, she sure loves her big sunglasses! “I must have 200 pairs,” she says of her massive collection of shades, which she says she hates to leave the house without – “especially when I have no makeup on and I’m going to the gym!”

Though her red-carpet attire is the envy of millions, Kim says she’s budget-minded when it comes to her clothes. “I love shopping at stores like H&M, Zara, and Forever 21,” she dishes. And her splurges? “Purses! I have a Hermès Birkin addiction.”

Think that famous figure comes easy? Think again! Kim’s current obsession is her tush-toning Skechers Shape Ups. “I have limited time to work out these days,” she explains, so “I wear these instead of hitting the gym sometimes!”

Kim swears her prep routine is low-key – as long as she’s just stepping out for the day. “When it’s just me getting ready, [it takes] 20 minutes, low maintenance.” But for a red carpet event? Set aside the whole afternoon: “When I get my hair and makeup done, and we take out time to get ready for a big event, it could take three hours!”
