The social-media savvy model constantly keeps us updated with not only her fabulous adventures (seriously, Zac Posen is her BFF) but with her always enviable hairstyles. Most recently she took to Instagram to show us her latest 'do—a cute, grown-out bob. Take a look at this look and take a look back at Rocha's other memorable manes.
