If there's one season where you should wear a ponytail, it's definitely summer.
For practical reasons, a pony is great for keeping hair out of your face, for when you don't want the humidity to wreck your 'do and when you want to keep frizz to a minimum.
And who better to show you how you can get a cute and stylish ponytail than celebrities?
One recent twist to the classic pony comes courtesy of Duchess Kate Middleton, who sported a half-up ponytail style at a First World War ceremony this week.
So get inspired by the best celebrity ponytails of all time for your summer hairdo.
