“Kim Kardashian's jet has a strict rule: no shoes, no eating, and don't touch anything.”

Kardashian bought a Gulfstream G650ER in 2022 and had it refitted with a light-grey cashmere interior — headrests, ceiling panels, even overhead bins. Cashmere and marinara sauce are natural enemies, which is where the rules come from.

In a 2022 episode of the Hulu series, her sisters were told to remove their shoes and were handed SKIMS slippers, and Kim shot down a request for pasta, offering waffles instead. The 'don't breathe' line was delivered as a joke, though the cameras made clear she was serious about the upholstery.

The jet itself is unremarkable by billionaire standards: a standard G650ER seating around 18 in the original configuration, reduced to a smaller lounge-style layout. The '$150 million' figure sometimes quoted is not credible — a new G650ER lists at roughly $70–75 million and a custom refit adds a few million more.

Whether a fashion-conscious owner asking guests to take their shoes off counts as a 'strict rule' is a matter of tone. It is certainly no stranger than the shoe policy at many people's front doors.
