Kim Kardashian is showing the world that she is a brainy beauty.

On Friday the 38-year-old Keeping Up With The Kardashians star posted a throwback pH๏τo for her 136M Instagram followers where she was reading a book while wearing a Sєxy little outfit that highlighted her trim waistline.

The mother-of-three captioned the pH๏τo, ‘Take notes.’

Kim had on a low-cut royal blue ʙικιɴι top that had a large cut out showing her tummy. And she had on what looked to be a sheer blue scarf tied around her waist.

The pinup was wearing mirrored sunglᴀsses with her hair down.

And she was holding a pen up while a blue book was in her other hand. The book had no writing on the front and looked more like a journal than a law book.

Her toned legs were positioned just so to accentuate her figure.
