Normally, when a star is caught in her underwear, the photo is shocking enough. But for Kylie Jenner, the most surprising part of this sexy ‘gram is the affordable price tag.

The 19-year-old took to Instagram on Thursday morning to share a photo in nothing but a bra and underwear, flaunting her toned bod. Jenner rocked a Pretty Little Thing nude sports bra ($18; and matching briefs ($18;, proving that sporty sets are just as sexy as lacy lingerie.

The Keeping Up with the Kardashians star has been keeping a low profile this week, cancelling appearances with her sister on The Ellen DeGeneres Show and The Late Late Show with James Corden, but she’s still been busy.

The 19-year-old and big sister Kendall recently announced the expansion of their fashion empire into eyewear, and the beauty mogul also unveiled her Kylie Cosmetics holiday collection on Snapchat, showing the shadows, glosses, and lip kits that will go into her holiday stocking.

Ah, life in the fast lane.
