The bun is one of the summer’s hottest hairstyles. It’s super-easy, keeps your neck cool (hallelujah!), and it’s oh-so-flattering on every face shape! If you have a heart-shaped face, i.e., wide forehead with a sharp chin — balance things out with a bun in the middle of your head. Elongate a round face with a low bun, Evita-style. Square-faced women should go for a bun with sexy, face-framing tendrils to soften a strong jaw. And a high, ballerina-esque topknot is super-pretty on oval faces. Need inspiration?
