I have a pretty standard butt: meatiest at the bottom but proportional. I'm no Kar-Jenner. I wanted to love these undies as much as I love Negative's bras, but despite the amazing sieve fabric and un-noticeable waistband, I won't be ordering more because these ride up all day long. There's just not enough fabric where it counts.
