Kendall Jenner sexy bra & underwear PHOTO goes viral on Instagram: Harry Styles' ex flaunts Calvin Klien intimates

Kendall Jenner sure is enjoying the perks of being a model.

The stunning 18-year-old "Keeping Up with the Kardashians" starlet posted this sexy snapshot on Instagram on Friday (March 14):

kendalljenner: "morning! just going to hang out in #MyCalvins alllll day! ... thank you @calvinklein for my little gifts."

Kim K's younger sister sure can make a simple pair of white bra and panties look hot!

Rumors initially suggested that Kardashian was dating One Direction heartthrob Harry Styles, but apparently that romance quickly fizzled out. Wonder if the 1D crooner's kicking himself now?

The fashionista also posted this retro pic on the popular social networking site:

kendalljenner: "Get our new @pacsun spring arrivals on April 4th! #kandk4pacsun."

Just living the glam life - Kardashian style!
