Looks like Kylie Jenner's channeling Kim Kardashian!

The "Keeping Up with the Kardashians" star showed off her much longer black tresses via Instagram on Monday.

The 17-year-old beauty looks gorgeous in the snap as she stares into the camera with her side-swept 'do on display. "pacsunn whaaaaart @joycebonelli long hair don't care," she captioned the candid photo.

We're guessing the reality star got the extensions for a new photo shoot with PacSun -- but doesn't she look great?

We think this is a vast improvement compared to the shoulder-length black and blue locks she's been rocking for the last few months.
