Whether on the red carpet or on the go, this summer's easy, breezy hairstyle is a casual top knot. Besides working with every hair type, this low-maintenance look provides instant polish to an outfit.

We weren't surprised to find that a ton of pop music's most popular singers have been photographed rocking this stylish bun. When we gathered our fave looks, we saw just how versatile this 'do is!

In the top row, Karmin's Amy Heidemann, Demi Lovato, Miley Cyrus, Carly Rae Jepsen, Taylor Swift and Bella Thorne showed that top knots work with everything from a smoky eye to a dramatic red lip.

The bun can also be sleek and slicked back or tousled and casual. In the second row, Beyonce, Cher Lloyd, Bridgit Mendler, Jennifer Lopez, Lady Gaga and Gwen Stefani each played around with styling their top knots.
