Kate Middleton’s Favorite Designer Is Now Hollywood-Approved

For almost as long as she’s been in the spotlight, Kate Middleton has been a style inspiration for women across the globe. (Ever heard of the Kate effect? Yeah.) Her spectacular taste in fashion hasn’t yet eclipsed her years of dedicated royal service, but it has come close. 

But while many British tabloids have followed the Princess of Wales’s personal style like hawks in order to predict what trends the land of beans on toast will obsess over next, Americans were more likely to look to a Kardashian for style inspo than a duchess. That is, until now.

Kate Middleton’s style has infiltrated Hollywood.

Both Margot Robbie and Ana de Armas have been spotted wearing tea-length polka-dot dresses by Alessandra Rich, one of the princess’s go-to designers, over the last few days. Though the brand has offerings with shorter hemlines, she always reaches for the more modest cuts, in polka dots—like the styles both actors wore this week.

While Robbie opted for a cerulean spotted dress while promoting her upcoming film Amsterdam, de Armas chose a simple black-and-white polka-dot dress during a visit to Late Night With Seth Meyers. Not only have the two actors famously played dead Los Angeles starlets (Sharon Tate and Marilyn Monroe, respectively), they’re now part of the Alessandra Rich fan club. It’s a rite of passage.
