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 DonateMyDress.org 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.
