Playboy: 268,403

Account Tagline: "See the world of Playboy through our eyes. Follow the official Rabbit for behind-the-scenes coverage you won't see anywhere else."

Why it's a great account: Playboy sticks to its sexy style on its Instagram account, but the images shown are much more PG than we're used to seeing from the company. The images are primarily of the Playmates in real life —in sexy poses, of course — versus in a photshoot. Here's a picture of Miss November on New Year's Eve.
