The dolly bun has been around for a while. It's a quick and easy way to pop your hair up, and is more interesting than a pony. Cue Jessica Hart who stepped out at the AmFAR Gala last night with a second generation dolly bun (dolly + doughnut = second generation dolly bun).

Instead of just twisting your hair and tying it in place, the doughnut gives the bun a larger, more fixed shape and it looks more polished than the original – perfect for special occasions. Jessica’s bun is slightly dishevelled too so it still has an effortless quality, but we especially love it because it's an affordable way to make a statement - you can pick up a doughnut at boots.com for £4.69.
