See which stars changed into second outfits to celebrate the night away.
After the show, it's the after-party and stars continued to serve gorgeous looks post-Emmys.
Some celebs who attended the ceremony changed into a second outfit (because why not!), while others joined the A-list crowd for the first time as they party hopped.
See the glamorous ensembles you can't miss from the star-studded soirees below.
Jessica Biel and Justin Timberlake made their way to hosts Michael Che and Colin Jost's party presented by Google (captured on Google Pixel). Biel swapped her stunning white bridal-esque Ralph & Russo number for a regal, bright yellow bustier gown by the same designer. Timberlake kept it cool by ditching his bow tie for the rest of the night.
Chrissy Teigen and John Legend was another adorable couple to check out the party circuit. While Legend stayed in his dapper, navy blue suit, Teigen changed into another silver dress -- this time a draped mini that showed off her long legs at the Hulu event.
Issa Rae arrived at HBO's post-Emmys reception in a color-blocked column dress with embellished straps, a departure from her custom Cinderella jumpsuit by Vera Wang.
Tiffany Haddish opted for a solid-colored blue V-neck long-sleeve dress from the rainbow Prabal Gurung gown she wore during the ceremony at the Celebrating the Culture Powered by Samsung Galaxy party.
