Got an important occasion that requires a little more of a fancy updo? Cara Delevingne has your inspiration covered. Her updo for the London screening of Carnival Row in 2019 was perfectly brushed up into a high bun and twisted together to create a topknot. What's really clever about Delevingne's look is that the accessory at the back acts as a clip for all of the loose pieces of hair that might not be long enough to fit into the bun. A smoothing product like Windle Shine & Smoothing Oil (£24), coupled with a stronghold hairspray, will also help keep all of the wispy pieces of hair in place.
