Regular shapewear rolls down at the waist, rides up your thighs and traps the heat all day. You still need a separate bra on top, and every trip to the bathroom means peeling the whole thing off in a tiny stall.
This bodysuit is one ultra-thin piece that feels cool on your skin, with a real bra built in, so you don't need anything else underneath. Firm compression smooths your tummy and waist, the shaped back lifts your butt without flattening it, and the back panel pulls down so you can use the bathroom without taking it off.
