Waist training (or corseting) uses corsets or waist cinchers to whittle down the size and shape of one’s stomach over time.
Khloé Kardashian also wore a similar garment earlier this summer, so it seems as if Kanye West's wife - who has made no secret of her desire to lose her post-baby weight - is taking advice from her little sister.
Earlier this month, the 33-year-old went on a Twitter rant about how frustrated she's been trying to lose the last few baby pounds.

She wrote: "Off to an intense workout. Can't seem to shake this last 15-20 lbs of baby weight. No more excuses. My baby is 1 years old! UGH!"
"I'm not gonna call it baby weight bc that's an excuse. I just gained weight & that's it. Why is it so much harder to lose after baby thought!
"Do any of u moms see their bodies just not the same? A different shape? Ughhh my hips & butt are huge now! They were big to begin with! Just need to get down to my weight a few years ago. Not gonna complain anymore. Starting diet TODAY! No carbs. Crazy workouts. Whos with me?"
North West's mother continued: "I think after having a baby u get so excited u lost a lot of weight then u get comfortable & eat how you used [to] & it creeps back up…For real….off to the gym! Wish me luck on the dieting…its soooo hard for me!"
