Say goodbye to the half-up/half-down bun – double buns have officially taken over as the trendiest cool #girl hairstyle of the season. It’s only fitting, considering how many other late 90’s/early 2000’s trends are considered stylish again. Double buns are also known as space buns, and they always make me think of my childhood obsession with the Spice #Girls. They’re cute, fun, unique, and easy to do – and they’re also super versatile. As it turns out, there isn’t only one way to do space buns.
