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!
