Increasingly, I think Lennox’s grown-up crop is a timeless option – it’s like the cut that Twiggy and Mia Farrow debuted in the ’60s, but worn by a woman in her 60s. Inspiration for this look is rich and varied and includes Dionne Warwick, 81, Jamie Lee Curtis, 63, and Judi Dench, 87. Curtis and Dench both keep their crop a silvery grey and the result is low-maintenance, flattering and modern. It also lets you play with make-up, colourful clothes and big earrings without ever looking too done-up.

‘I love Judi’s razor-sharp pixie cut in particular,’ says celebrity hairstylist George Northwood. ‘If you’re opting for a shorter style like hers, just make sure to maintain it correctly so that it looks sophisticated. Shorter hair still needs a little bit of maintenance, but nothing too drastic. Also think about whether you want an asymmetrical crop with a longer fringe, which is a bit messier and more undone, or a super-short, sleek pixie crop.’
