Kim even matched the decor at the event.
Kim wore a vintage Jeremy Scott trenchcoat and matching boots to the event, and paired the look with a Judith Leiber money bag purse valued at nearly $4,000.
She shared a sneak peek of her outfit in a mirror video before heading out.
"What do you do when your friend sells her company for a couple billion? You wear a full money fit and throw her a party," she shares in the clip.
Say what you want about Kim, but she knows how to put a look together.
I love everything about this. From her hair pulled back so that it doesn't distract from the outfit to those trendy tiny sunglasses--this is a look.
Even the music choices at the party went along with a theme.
While inside, Kim danced and sang along to Rihanna's "Bitch Better Have My Money." How appropriate!
But let's not forget, this look has already been done before.
Jennifer Lopez appeared on Jimmy Kimmel! wearing a full dollar sign outfit in June, but as we already know J.Lo has been inspiring people's styles since the beginning of time.
