Babe of the Day — Bruna Lima

Bruna Lima belongs on any "Best Booty on Instagram" list, and she wants you to know it. Half her feed is pics of her from behind, usually in some paper-thin bikini (of her own design).

It's an effective marketing technique, as we are now convinced that these bikinis are magical and perfect and will make every man who sees them stronger and smarter and better-looking. Thanks, Bruna!
