Diane Keaton’s iconic career is packed with so many signature menswear-inspired style moments, her look has become as famous as her roles. So it’s no real surprise that stars came out in full fashionable force Thursday night for an event honoring her achievements.

Rachel MacAdams led a bevy of fabulously dressed celebrities who paid homage to Keaton at the American Film Institute’s 45th Life Achievement Award Gala Tribute to Keaton in Hollywood. The “Spotlight” star, who spoke at the event, dropped jaws in a perfectly fitted floral Johanna Ortiz gown.

Other notable mentions included a super blonde Emma Stone in a printed long-sleeved Loewe dress, Meryl Streep in a Keaton-esque tie and, of course Keaton, looking more like herself than ever. Check out the exceptionally stylish event below.
