A host of celebrities sported variations of the topknot at the Billboard Music Awards, proving the versatility and weather-friendliness of the look. Actress Keke Palmer showed off her shaved sides and choppy bangs with her updo, while Jessica Alba let her ends hang loose with a Samurai-style topknot. Singer Ciara — who's becoming a hair favourite of ours — wore her knot lower and in a messy half-bun style that is all the rage now. Mila Kunis' almost demure ballerina style did not detract from her gown, giving her a clean silhouette and neckline. If you want hair that stays up so you can hang loose and doesn't mess with your jewellery or outfit, this is the style for you.
