Michelle Obama graces this week’s cover of Variety.

In the interview, the first lady discusses her four major causes: Let’s Move (promoting healthy eating and exercise), Joining Forces (providing veterans assistance) and education initiatives Reach Higher and Let Girls Learn.

As one of the highest-profile women in the world, Obama also has a major influence on fashion. She’s elevated ready-to-wear by donning pieces by J. Crew. She’s cemented the star status of Naeem Khan and Carolina Herrera by regularly wearing their designs to state dinners. She’s promoted emerging talents, including Cuban-American Isabel Toledo, who created Obama’s now infamous lemongrass dress and coat she wore during her husband’s first inauguration.

For the cover, she donned a dress by Jonathan Simkhai, who won the CDFA/Vogue Fashion Fund last year. “It was a huge honor and brand milestone to work with Michelle Obama’s team on a custom dress for the cover of Variety,” Simkhai told WWD. “Michelle represents the definition of a strong, fearless, inspiring and truly elegant first lady, and seeing her in one of my dresses was a dream come true.”

The first lady isn’t afraid of taking more risks than her predecessors, wearing sleeveless gowns, flared skirts and bold colors like yellow. And she’s not afraid to reuse looks; among her favorites is a white Prabal Gurung dress she wore to the Smithsonian in 2010, a dinner for the Bush family in 2012 and Easter service in 2013 (below left). She’s also upcycled dresses by Tracy Reese.
