Olivia Palermo hits Soho, NYC, for Tibi's Spring 2011 ad campaign.

Tibi is mixing it up for Spring 2011.

The label has cast reality star and socialite Olivia Palermo for its latest campaign, which takes a more informal, street-style approach, Who What Wear reports.

Eschewing polished photo shoots, Tibi instead asked Palermo to select the outfits she'd like to wear and style them herself with her own accessories. Photographer Reed Young then snapped the star against a series of fake backdrops representing New York, Paris, Milan, and London.

"Combining our love of the fashion-blogging world with a quirky element of fun, our Spring '11 Web campaign is a twist on the very authentic snapshot of individual style mixed with a contrived setting of the very fashionable cities our style icons are snapped in," the Tibi blog reveals.
