Kate Middleton proved that tartan will be this season's print de jour when she stepped out at her old prep school, St Andrew's, donning a plaid Alexander McQueen dress and it didn't take long for a hoard of celebs to follow suit.
We can always rely on Kristen Stewart and Jessica Alba to give us wearable style inspiration, and they've both been spotted styling up tartan trews.
While K-Stew trailed the trend in Juicy Couture cigarette pants, Jessica favours a more casual approach as she stepped out earlier this week in Current/Elliot's checked denims. The celebrity fashion trend has also travelled across the pond, as Brit fashionista Anna Friel was seen exiting the Vaudeville Theatre in a pair of tailored plaid skinnies.
Cue a hot new trouser trend!
