By now we're used to getting intimate peeks into Kim Kardashian's private life. But on Thursday night (Aug. 9) the Keeping Up with the Kardashians star really pulled back the curtain before hitting the town to celebrate her little sister Kylie Jenner's 21st birthday.

In a post that has already racked up more than 3 million likes, Kardashian asked her followers a very simple question: "Hmmm what should I wear tonight?" while posing provocatively on the floor of her closet in just a thong and green bra.

 

Hmmm what should I wear tonight?

She was, of course, getting prepped to join the rest of the clan for Kylie's party, which they all documented with plenty of snaps. "Happy 21st birthday @kyliejenner baby!!!!! It’s such a trip that my baby sister is 21 -- So happy to be on this sister and now mom journey with you forever!!!!" Kim wrote. "I love you so much! You will still always be my baby sis and I’m always here for you no matter what!"
