Kendall Jenner, the second youngest member of the Kardashian-Jenner clan, recently decided to take it all off in an advertisement for underwear. The star isn't shy about showing off her body, and her Instagram is filled with racy photos. Kendall has also been photographed several times in white shirts that are see-through.

For the Fourth of July, the star even celebrated America's independence by appearing in a see-through top and posing with her thumbs hooked in her underwear. Because of Kendall's willingness to bare it all, it shouldn't be a surprise that she's decided to forgo her clothing for a new ad campaign.

Kendall's ad

The supermodel posed topless, wearing just underwear, for La Perla, the notoriously expensive and luxurious underwear that only people like Kendall Jenner can likely afford. The racy photograph was also posted on their Instagram page with the caption, "Introducing La Perla's #FreedomPanty, crafted from the finest French Leavers Lace with interwoven stretch. Shop online and in our boutique."

Kendall Jenner's new ad has already been criticized, however, for looking like it might actually be a plastic model of Jenner instead of the real deal. Although her sister, Kylie Jenner, recently had a mold of herself placed in Madame Tussauds, fans have joked that the photograph of Kendall actually looks like the La Perla ad looks more like it belongs on the display floor next to her sister's wax model.

Plastic surgery criticism

Although Kendall Jenner is known as the most natural of the Kardashian-Jenner sisters, the star has been criticized in the past for having plastic surgery, which fans have speculated about for several years. The star allegedly has had a nose job, as well as butt-implants in order to make her lower half appear more rounded like her half-sister Kim.

However, she has not acknowledged any of these rumors, in true Kardashian-Jenner fashion. Her younger sister, Kylie Jenner, has been accused of having breast augmentation rather recently, though she has also kept mum about the accusations.

The star is perhaps the least curvaceous of all of the women in her family, which likely makes her perfect for modeling.

Her mother, Kris Jenner, was recently accused of getting butt-implants herself, though Kris unsurprisingly, Kris has also kept silent.

No matter what the star wears, or doesn't wear, it is pretty clear that she has a long career in modeling ahead of her.
