Miserable: In last weeks episode of The Kardashians,  Kourtney – pictured above in old photographs from when she weighed just 95lbs – said she was unhappy at her at her thinnest. She explained: ‘When I was super skinny, it’s like a time I was super anxious, not about eating, not about staying at a certain weight, but like just in like toxic relationships’

In another close-up snap, the star showed off the back portion of the gown, which was secured and held up with a heart-shaped silver chain towards the bottom.

The backless side revealed some of her recent cupping scars from the therapy procedure. 

Cupping is a current popular form of alternative medicine that aims to help ease and manage pain, blood flow, inflammation, and promote relaxation, as reported by WebMD.  

Her dark hair was parted in the middle, and fell down straight with the tips lightly brushing her shoulders.

In another photo, Kourtney adorably flaunted her husband’s socks and a glimpse of his boxers under the pink dress as posed for an additional snap.

The last snap the media influencer uploaded was a mirror selfie that she took with a digital camera.

Kourtney added during the third episode of season two, ‘Having a partner who is so supportive of me and always complimenting me, no matter what, it’s just helped me to really embrace the changes and actually to the point where I love the changes now.’
