Life's a beach if this summer's most ubiquitous trend is anything to go by. Once only worn on holidays, now shorts have become a wardrobe staple, turning up in offices and nightclubs too.
And despite tumbling temperatures, the leggy look is going nowhere for winter.
"It's one of my favourite trends," says top stylist Marietta Doran. "I've even got a 'Shorts' album on [social network] Pinterest!
"Sometimes you don't feel like wearing a skirt, but you don't want to wear trousers either. Shorts are a great in-between style.
"But the best thing about wearing shorts in winter is that you don't have to worry about whether your legs are tanned – just throw on a pair of black tights!"
Olivia Palermo, Kate Moss and Jennifer Aniston are just some of the stars taking short cuts when it comes to style.
"Shorts are surprisingly wearable," adds Marietta. "Of course, teenagers are going to copy Rihanna's Daisy Dukes, but longer-line shorts can actually be very flattering.
"For autumn/winter, tweed, leather and graphic print shorts are going to be huge," she says. "Team them with a crisp shirt and blazer for work, then simply change into a sequin top to go from day to evening.
"If you've got long legs, wear them with pumps; if not, go for high heels!"
1. THE COMEBACK SHORTS
Is it a short? Is it a skirt? No, it's culottes! If you're a child of the Eighties, chances are you wore a pair of these bad boys for your Confirmation. Well, let's hope you held on to them because 'skorts' are back in a big way this autumn.

7. THE SORT-OF SHORTS
