Some people get tan lines. Others like Kylie Jenner get tan malfunctions.
As the sun shined bright in Calabasas, Calif., Sunday afternoon, the Keeping Up With the Kardashians star decided to show off her fit body in workout gear.
But while posing in her sports' bra and short black shorts, the E! star also revealed the secret behind her tan.
"Love my @CocoaBrownTan from @MarissaCarter when I want a fast tan," she wrote on Instagram. "#SelfTan #CocoaBrown #1HourTan."
While we're more than a bit envious at how Jenner got so tan so fast, we can't help but notice a few spots she may have missed.
From our angle, the E! star's right leg looks like perfection. The left side, however, has a few lighter spots. Perhaps we can suggest the fashion designer to reapply? Or maybe, she's just trying to prove the power of Cocoa Brown Tan!
Putting beauty products aside, the 17-year-old is ready to enjoy another summer as a teenager. After all, Kendall Jenner's younger sister realizes time is going by so quickly.
"I'm scared of the day I turn 19," she recently shared with The Sunday Times. "I really don't want to grow past 18."
Relax, doll. You have most of the summer months to enjoy yourself. But beware, that 18th birthday on August 10 will be here before you know it.
