Kardashian fans accuse Kim of copying Kourtney's signature style detail with bold new look amid sisters' bitter rivalry

FANS have slammed Kim Kardashian for seemingly copying her sister Kourtney's signature look in a new video.

Backlash ensued after Kim, 42, appeared in a TikTok video on Monday, showcasing her makeover.

In the clip posted on her shapewear line, Skims' account, Kim boasted about the brand's new Ultimate Bra.

It first showed her gushing over the product while on the phone and later modeled the bras for the camera.

However, many viewers were more focused on the beauty mogul's changed appearance as she sported a shorter hairstyle.

Kim ditched her former long locks for a short cut that stops at her chin - a very similar hairdo to her sister Kourtney's.

FAN'S REACTIONS

One fan pointed out the similarities in the sisters' looks on a popular Kardashians forum by sharing screengrabs of Kim's hair in the video.

"Kim is Serving Kourtney Bob Realness," they wrote in their caption, starting the discussion.

"Looks better on Kourtney," someone claimed in the thread.

"Yikes, it looks much better on Kourtney," another echoed.

"Lookin absolutely ridiculous with that wig," a third mocked.

"All she do is copy," called out a fourth.

"That bob looks so much worse than Kourt’s. I’m pretty sure Kourtney’s is real hair and Kim’s is another bad wig?" chimed in a fifth.

This isn't the first time that Kim's been accused of mimicking Kourtney's style, as the siblings have been embroiled in a nasty feud for months.

In July, Kim flaunted a short haircut on her Instagram Story while promoting new clothes that dropped for Skims.

Fans again couldn't help but point out it looked just like Kourtney's short bob and called Kim out for the move.

"She stole her hairstyle!! Lol," one person wrote in an online thread.

"Unlike Kourtney’s hair, Kim’s is all fake," another commented.

In April, fans thought Kim copied Kourtney's looks while enjoying a family trip to Japan.

In an Instagram post, Kim and her children Saint, seven, Chicago, five, and Psalm, three, posed by a photo booth.

Kim sported an all-black attire with sunglasses and a pair of silver boots.

"She wanna be Kourtney so bad," one critic claimed in a thread where fans discussed the photo.

And someone else shared the same thought: "She def wants to be Kourt."

It came shortly after drama erupted between the siblings on their Hulu series, The Kardashians.

During the episodes, Kourtney accused Kim of copying her looks from her wedding for her Dolce & Gabbana fashion show.

Kourtney, 44, married her husband, Travis Barker, 47, in an elaborate ceremony in Italy last May, entirely dressed by the designers.
