Few hairstyles are chicer than the topknot right now — it’s the look on runways and red carpets — and ladies, we really have Kourtney Kardashian to thank. A couple of years ago, she made the sleek high bun her signature, rocking the glam style to events and on Keeping Up With the Kardashians (and its spin-offs!). Soon, all of her siblings followed suit (sans Rob, we assume), which inspired a slew of ¬†“Kardashian topknot” tutorials on YouTube.

Whether it’s a tight chignon (favored by Kim) or an undone bun (hi, Khloe), these girls have cornered the market on cool upsweeps.¬†Check out our 10 favorite looks from the Kardashian hairstyle files!
