Kim Kardashian doesn't need a high school reunion to show her former classmates what she's been up to - she's one of the most followed celebrities in the world.
The middle Kardashian sister teamed the racy garment with a pair of clear designer heels.
According to what Kardashian insiders told The Sun, Kim's smiling face in her new Instagram photo may be hiding her anger at Tristan Thompson.
She begins by sharing that she rented a party bus for her and her Marymount alumni friends.
The mother-of-three pans around to show some of her friends before explaining a new concern.
"So my friends are anxious that we're going to run into people that they were mean to", she said.
And the Photoshop accusations are set to continue, as Kim has revealed that she deleted and re-posted holiday pictures after editing them.
While the reality star is will be busy re-branding her social media page, she is also standing by Khloe's side in the midst of the Tristan Thompson drama.
Envious! 'We are walking the same halls we walked 20 years ago, ' she says in wonderment, while others comment that they are 'much nicer now'.
Kim and her sister Kourtney Kardashian seemed to be playing a game of who-can-wear-the-tiniest-bikini, with the Kardashian siblings only taking time away from the swimsuit showdown to post a photo together for National Siblings Day.
She went back to school! Thompson also flew from New York City to join Khloe before their daughter came.
