Bombshell one day, coastal grandmother the next pretty much sums up Anne Hathaway's recent style transformation. After stepping outside her sartorial comfort zone at Cannes Film Festival this week in a slew of stellar looks (see: Anne in a minidress with a built-in conical bra made out of latex), the actress dove deeper into unfamiliar fashion territory in an outfit that was less glam, and well, more grandma — but nonetheless, still chic.

On Saturday, Hathaway was spotted arriving at the airport wearing a polished white button-down tucked into a pair of wide-leg jeans. She accessorized with pale yellow strappy sandals, and an accessory that epitomized the coastal grandmother trend: a black and white floral crochet bucket hat. Meanwhile, a blue quilted jacket was slung under one arm, and a black Bulgari tote with a silk scarf from LilySilk tied around the handle was underneath the other. Anne's dark hair was worn down and styled straight, and she seemingly went makeup-free beneath her oversized square sunglasses.

We counted not one, but two (arguably maybe three) grandma-chic trends in her travel-ready outfit.

This week, Anne made her Cannes debut to promote her new film Armageddon Time, a coming-of-age drama about growing up in Queens in the 1980s. Hathaway stars as Esther Graff, a Jewish mother, and during a press conference for the film, she said it was "honor" to take on the role. "My mother-in-law, who passed away recently, was simply the greatest Jewish mother I've ever seen. Her legacy influences my life in profound ways that I am truly, truly grateful for," she shared. "The hand of a Jewish mother will guide the rest of my life, if I have done one thing and it is to capture that love, I honestly won't even attempt to put it into words."

She added, "That's why I am so grateful to cinema because it allows you to say things without words."
