It's no surprise that singing sensation Dua Lipa and actress Millie Bobby Brown look amazing in bodysuits, but which babe are you going to choose?!

While only one of them is comin' out on top, both babes def felt cute and took it to the 'Gram to show off their curves in sexy shape wear!

Dua's doing her selfie-in-a-mirror thing with a spaghetti-strap black bodysuit fastened on both sides of her bod, with dangling gold earrings, looking almost ready for a night out on the town ... while Millie's got more of a daytime 1980s-workout vibe, with knee-high tube socks and nude tights, wearing a heather-gray bodysuit featuring long sleeves, in an airy studio.

So we gotta ask -- which look do you prefer ... dark and sultry, or bright and bouncy?

And while you're at it, see if you can guess these Hollywood hotties who hopped on the shape wear trend!
