The jeans and tank top approach to heatwave dressing is nothing new. But if there’s one star who’s perfected the art of stripped-back, off-duty chic, it’s Zoë Kravitz, whose ’90s minimalist style has (and continues to have) social media in a chokehold. Every day, there’s a new inspo account cropping up on my feed: you can try to unfollow them all, but like Medusa, cut one head off and three more crop up.

Now, it seems that Margot Robbie has officially enrolled in the Zoë Kravitz school of dressing. Stepping out in London after a stint at Glastonbury, she perfected the formula: black tank top, straight-leg jeans, and the inescapable Alaïa mesh ballet flat. Strange shoe-induced tan lines aside, her low-key look was the perfect incognito cover to blend in with the army of tank-and-jeans girls currently pacing the pavements of every zip code, with only her Phoebe Philo bag hinting at her A-lister status.

Perhaps it’s the softening influence of an oppressively hot London summer, but Margot Robbie’s pared-back off-duty look is a million miles away from her much documented Barbie press tour. Plus, it was topped off with the most important city accessory of all: the anti-snatch phone strap.
