BACK TO SLIDE
Khloe Kardashian turns 30 today, and her sartorial point of view has never been better. Since coming into the spotlight during the mid-2000s, the Kardashian klan have been a major part of popular culture, and the world has followed their every move -- and what they're wearing while they do it.
While we've been "Keeping Up" with one Kardashian primarily as of late (new mom, Kim!), and are basking in the delight of having Kendall and Kylie as Guest Editors, of course we can't forget the rest of the family. Khloe's witty commentary and happy-go-lucky attitude always keeps us laughing, but even better, her style is consistently on-point.
Happy birthday, Khloe!
