Waist training with a gold belt? Only when you're a Kardashian!

Posting pics on Instagram, Kylie Jenner stole sister Kim Kardashian's oversized t-shirt style and paired it with a Balmain Gold-tone waist belt, which retails at $4,295.

We have no idea why these sisters are loving this baggy shit look -- but Kim's been doing it for weeks now and it looks like Kylie's jumped on her band wagon. But what's new Kylie is just the poor man's Kim!

The newly blonde bombshell seems to be soaking in life in the lighter shade -- but we're a little sad to see she's stealing Kim's too-baggy shirt style -- it's the worst!
