Contrast-collar blouses have been quite popular since they burst onto the fashion scene, especially among celebrities like Bérénice Bejo, Jamie Chung, and Jenna Elfman. What's great about them is that they can just as easily work at an office environment as they can out on the town. We love that Bérénice chose Carven's colorful zigzag contrast-collar blouse and how she tamed the bright colors via black. Jamie wore her sleeveless contrast-collar blouse in a more party-appropriate way, while Jenna opted to button her blouse all the way for a hint of menswear.
