Leave it to Lupita Nyong'o to bring it with the red carpet color. On Monday, the queen of twirling for the cameras arrived to the Accessories Council's 2018 ACE Awards in a bright yellow sleeveless Carolina Herrera dress that won our pick for best-dressed. She was on hand to honor her stylist, Micaela Erlanger, with the Style Influencer Award, and also caught up with another honoree, Style Ambassador Award recipient Tracee Ellis Ross.

While summer can be sleepy in Hollywood, there were plenty of red carpets to pay attention to in New York. At the 2018 Tonys, Kerry Washington shone in a plunging Atelier Versace silver jumpsuit, while a cast of fashion insiders like Naomi Campbell and street style favorite Olivia Palermo made it out for the Fragrance Foundation Awards. Of course, there were waves of empowering messages sent at the Max Mara Women in Film Face of the Future event and the WIF Crystal + Lucy Awards. Later, Olivia Wilde teamed up with True Botanicals for a benefit dinner in support of Time's Up.
