Kim Kardashian sparks concern as she looks even thinner than sister Kendall Jenner in rare pic at home

KIM Kardashian has sparked worries about her seemingly tinier figure after a pH๏τo showed her looking thinner than her runway model sister, Kendall Jenner.

Comments poured in about Kim’s pin-thin frame after she posted a snap of the sisters in honor of Kendall’s birthday.

On Friday, Kim, 43, took to Instagram to share a carousel of throwback pics, including solo sH๏τs of Kendall, 28, and some of the siblings together.

One, in particular, raised eyebrows as it showed the duo slumped on the couch while dressed in silky floor-length dresses.

Kendall rocked a silver dress with a halter top, and Kim wore a metallic green-colored number with a large cutout along her midsection.

They had their bare feet on the coffee table as they smiled at the camera.

Kim wrote a heartfelt message in her caption for the birthday girl, but many fans couldn’t help but notice the star’s seemingly smaller physique compared to Kendall’s.

The post was shared on a popular online thread where one person commented: “[Kim] looks weirdly like a skeleton.”

Another added: “What is their obsession with looking smaller than ever?” while a third remarked: “She looks frighteningly small.”

Earlier this week, Kim turned heads when she ditched her pants for a ɴuᴅᴇ bodysuit embellished with Swarovski crystals.
