We’ve seen almost every celebrity wear this hairstyle on the red carpet, including Mandy Moore here, and it’s no surprise why. It’s chic, it shows off your face and it’s easy to do. Plus, once your hair is up in a bun you don’t have to worry about it all night — no flyaways or frizzy/sweaty hair getting stuck to your face after you’ve hit the dance floor. And there are a million ways to wear a bun: low and sleek, high and messy, and everything in between.
