This event is almost as big as the Oscars. The main event is done. Stars change their outfits and let their hair down.
They all chill out that little bit more. It's less about looking prim and proper, yet, still making fashion statements.
Here's some of our favourite looks from the party.
Constance Wu - We're loving the sequin vibes.
Angela Bassett - The colours, the suit, the print. We're obsessed.
Megan Mulally - Yes, we're pretty sure that's an eagle on her neck.
Olivia Wilde - We're genuinely lost for words. Just flawless.
Catt Sadler - Proving that black is timeless, oozing pure elegance.
Olivia Munn - Rocking burgundy.
Kendall Jenner - The shoulders. Enough said.
