Given her longtime partnership with Chanel, it’s rare that something Kristen Stewart wears—especially for a press event—can be re-created easily on a budget. So when the Spencer actress appeared on The Late Show With Stephen Colbert wearing a basic that 1) can be purchased almost anywhere at an affordable price and 2) is essential to any well-rounded wardrobe, we knew we had to spread the news ASAP.The basic in question? A poplin, button-down shirt, aka every fashion person’s go-to when they need something stylish and put-together to pair with jeans, trousers, or even joggers (a WFH favorite). For her appearance on The Late Show, Stewart and her stylist, Tara Swennen, paired a white tuxedo-style button-down with cropped, high-waisted trousers; a black satin necktie; and cream-and-black lace-up pumps, all by Chanel. Underneath the unbuttoned shirt, she added a simple white tank top and silver jewelry.Though her head-to-toe Chanel look won’t come cheap, most of the look-alike button-downs ahead won’t cost you more than $150.
