Who knew the barbaric fashion practices of the Victorian era would be so on trend in 2015?!

Khloe Kardashian is keeping up with this ridiculous waist training fad by flaunting her ridiculously small corseted waist in a colorful selfie. Umm that looks painful!

On Thursday, the Keeping Up With The Kardashians posted the selfie which highlights her insane curves in a neon workout ensemble and hot pink waist trainer.

Along with the snap, Khloe wrote, "Who doesn't love a good waist trainer/bathroom selfie 😝 make sure you follow my girl @premadonna87 @waistgangsociety for the best trainers in the game. Head over to www.whatsawaist.com to get hooked up!! ❤️❤️❤️ lets snatch that waist 💋💋💋."

This isn't the first waist-cinching selfie the celeb has shared -- three weeks ago, Khloe posted a pic of her in an all-black ensemble, rocking another corset.

In that photo, she wrote, "I'm obsessed with the gym but a little extra help never hurt nobody… once you try it, you will become obsessed!!!"

The controversial beauty practice has us all at the X17 offices baffled -- but those Kardashian gals seem to swear by it.
