Kim Kardashian West has her own theories as to the events that led up to her being robbed at her residence in Paris, France, last October.
In a preview clip for Sunday's episode of Keeping Up With the Kardashians on E!, the 36-year-old reality star and her sisters, Khloe and Kourtney Kardashian, discuss how the men that robbed Kim at gunpoint were able to pull off such a heist.

"If you wait across the street, you can see the light is on, because we're the first floor," Kim explains. "So, they must have been told we're the first floor."
"They definitely were watching you guys," Khloe chimes in.

Speaking to camera, Kim goes more into detail about the robbery. "There was probably a group of guys that were following us the entire trip," she says. "I was Snapchatting that I was home, and that everyone was going out. So, I think they knew, [bodyguard] Pascal [Duvier] was out with Kourtney, and that I was there by myself."
"They had to of known we were leaving that day," she continues. "They had this window of opportunity and just went for it."

In January, the police report from Kim's robbery was obtained by Le Journal du Dimanche, and detailed her initial account of the crime. "I saw two men coming who were hooded, plus the hotel receptionist who was strapped; one had a ski mask and a cap and jacket with 'Police' written on it and one had ski goggles. He snatched my Blackberry," she stated in the report, according to the newspaper. "I was wearing a bathrobe, naked underneath. They pushed me on the bed and strapped me with plastic cables, taping my hands, mouth and legs. They carried me into the bathroom, more specifically, the bathtub."
Needless to say, the traumatic robbery has changed Kim's overall outlook, including her style. "I know it’s shocking to say Kim Kardashian is dressing for comfort," a source close to the mother of two -- who is seen nearly makeup-free on KUWTK -- told ET. "But when a life-or-death moment happens to you ...you're not really that interested in anything else. She doesn’t care about the smaller things in life."
