Kris Jenner fights back tears as she and daughter Kim Kardashian West sort through Caitlyn Jenner's old clothes in a sneak peek of Sunday night's episode of Keeping Up with the Kardashians

It’s been months since Caitlyn Jenner revealed her groundbreaking transition, but for ex wife Kris Jenner the reality remains hard to process.

In a sneak peek released by E! News from Sunday night’s new episode of Keeping Up with the Kardashians, the 59-year-old fights back tears as she and daughter Kim Kardashian West sort through Caitlyn’s old clothing.

“Caitlyn let me take this,” Kardashian West tells her mother, dropping a pile of garment bags containing the Olympic athlete’s old suit jackets and polo shirts.

“I didn’t have the nerve to open the bag,” Kris says while wiping away tears.

Kim notes that several of the designer duds were from significant occasions during the former couple’s 22-year marriage, and suggests that her siblings each pick an item of clothing to hold onto.

“It smells like him,” the 59-year-old says as she smells and then clutches tightly to a velvet jacket.

“I think going through something like this is difficult because the whole thing is something I’ve never dealt with before, and I realize that I still have a long way to go before I can process all of this and understand it,” Kris says in the clip. “And seeing these clothes and realizing that Bruce has thrown them out makes it real.”

Kris remarks that “it’s just crazy that he’s gone,” but Kim argues the opposite, telling her mother “no, he’s not.”

What Did Kris Jenner Know about Caitlyn Jenner?

Caitlyn’s new name is now official: on Friday, a judge approved her request to be legally declared a woman and officially change her name. She had initially filed for the name and gender change in the Los Angeles Superior Court on Sept. 13.
