The Problem: Mom Butt
A flat, elongated backside, without any shape or definition. Particularly noticeable when wearing jeans (a.k.a. flat butt, frump butt).

The Solution
Look for panties with posterior padding or shapewear with butt-lifting properties, says Nethero. Glassman suggests jeans with defined rear pockets and strategically placed darting and seams. Finally, wear heels: "They improve posture and lift the butt," he says.

Jeans with small back pockets; high-waist pants.
