The Kardashian-Jenner sisters are getting their “waists right.”

Kylie Jenner shared a selfie on Instagram featuring her and sisters Khloé Kardashian and Kourtney Kardashian sporting waist trainers, which have become a hot trend in the celebrity fitness world. Stars use the corset-style garments to accentuate their hourglass figures.

“Posted up with my babes getting our waists right,” Jenner, 18, wrote alongside a photo of the sisters.

Khloé, 31, has been vocal about her love of waist trainers.

“This band makes me sweat more in our tummy area so it give me that extra boost when I m feeling a little bloated. I love how my posture in the gym is even better due to wearing it,” she captioned a photo of herself sporting a waist trainer in November.

The new photo comes after Khloé returned to the gym after a two-month break following a tumultuous few months, which included estranged husband Lamar Odom‘s health crisis.
