The reality star put on a sultrier display by posing topless in a second snap.

Kim had her arms raised in her first pH๏τo and gazed into the camera with her head tilted.

She wore two long raven braid extensions that were swept over her shoulder.

To advertise her KKW Crystal fragrance collection, she had chunks of various crystals and gems by jeweler Jacquie Aiche tied into her braid, along with what appeared to be an old coin and a metal feather.

Kim’s hips were covered in a pair of her Skims shapewear, and she had her hands held up and resting on her shoulders.

‘RESTOCK ALERT. You asked, we listened — I am so excited to announce that in addition to the 3 new Crystal scents, we will be restocking our ENTIRE @KKWFRAGRANCE Crystal Collection in 30ML!’ she captioned her announcement.
