Kendall Jenner, the 16-year-old half-sister of Kim Kardashian, shows off her underage body in a new photo shoot for swimsuit maker White Sands. Kendall is gorgeous, but looks awkward posing.

Although she lacks the professional polish of a working model, in this “Black Swan” style shoot entitled “Pirouette,” there’s no denying she has model looks and body.

Fortunately, the swimsuits are all modestly cut with a vintage look. She poses in both bikinis and one-piece suits. The designs are also very feminine, with lots of frills and free-flowing cover-ups.

“The collection has both an ethereal and strong side and we wanted a model that could capture both,” Designer Leah Madden told People.

“As we were casting for the campaign we came across Kendall’s portfolio and loved her softness and strength. She actually made it to the top of our list before we knew her background,” she claimed. “Kendall was a delight on set and a natural in front of the camera.”

Kendall, who is signed to Wihelmina Models, has previously won contracts with Forever 21, Luca Couture, although White Sands Summer 2012 campaign is her first professional swimsuit deal.

For her part, Kendall gushed about the shoot on her blog. “I recently did a shoot for this amazing swimwear company, White Sands Australia, for their Spring 2012 look book and I can finally reveal the pics!

“This was my first professional swimwear shoot and I got to wear the most gorgeous bathing suits and cute coverups… what do you guys think of the pics?”
