The not-at-all socially distanced bash came just days after the Kardashian/Jenner clan copped a big online backlash for celebrating Kim's 40th birthday by flying to a private island for an extravagant week-long celebration.
Kim and co were accused of being "tone deaf" for flaunting the opulent holiday in the midst of the global coronavirus pandemic.
Days later and perhaps Kim was feeling sheepish as she opted for a surprisingly low-key Halloween look, keeping her body hidden under a red morph suit for this alien-inspired outfit:
Other contenders for best dressed at the party include Kylie Jenner for her King Cobra-inspired look, and singer The Weeknd who went as Eddie Murphy in The Nutty Professor, prosthetics, fatsuit and all:
And, just in case you needed yet more reminding of the Kardashians' obscene wealth after the private island holiday and the birthday hologram of last week, Kim shared footage of her own Halloween decorations on Instagram. They're... a lot:
Kim and her entourage had earlier jetted out of Los Angeles for her controversial birthday celebrations on a Crystal Cruises' Boeing 777-200LR, which features 88 flat beds, a restaurant and a bar.
The five-day trip reportedly cost the beauty mogul upwards of $US1 million ($A1.4 million).
