Heidi Montag is all about milking the attention. Former "The Hills" castmate Lauren Conrad, however, is all about the milk.

The budding novelist wore a stylish navy jumpsuit to launch her new campaign for Got Milk?, in which she's seen sporting a fetchin' milk mustache, a pretty printed maxi dress, and long, loose waves.

And Conrad has the public to thank for her chic ensemble. Body By Milk asked Facebook fans to weigh in on which style Conrad rocked for her ad, with $1 going to for every vote recorded.

As we can see, the beachy "California Girl" option -- which also includes sexy wedge espadrilles and a white floral clutch -- was the big winner, beating out "Night Out," a glam metallic cocktail dress and gold peep-toe heels.

Of course, it may take more than a glass of milk to nab this young fashion icon's look (though it's a start).

The BodyByMilk Web site is also featuring style and beauty tips from Conrad and her team of stylists offer the lowdown on the latest trends.

Well, that's our weekend planned...

Meanwhile, see which "Twilight" star is following in Conrad's footsteps.
