Between growing her fashion empire and penning her fourth novel, The Fame Game, Lauren Conrad swears she's too busy to focus on her love life right now. However, The Hills alum still knows a thing or two about looking hot. 

"First date outfits are very tricky," she says in a new video for Glamour. "You want something really sweet and pretty, but you want to bring in a little of a cool factor."

The 26-year-old  also shares the secret to her signature girl-next-door style: "Being sexy is picking one thing to show off, whether it's your shoulders or if you want to wear a shorter skirt," she added.

And when it comes to cleavage-baring looks, Conrad is all for it. "If you've got it, flaunt." She then caveats, "You can definitely go too far with cleavage…you don't want it to be the first thing people notice."

But the one area where she doesn't hold back is her shoes: "The higher the better," she says. "As long as you can walk in them, you're fine."
