Reality star Kim Kardashian West is clapping back at brands she says are copying her latest looks for profit.
During this year's Hollywood Beauty Awards event, Kardashian West wore a black vintage cutout dress from designer Thierry Mugler's 1998 archives. The dress initially made headlines for being revealing, but now an identical version of it has surfaced on giant fashion retailer Fashion Nova's website for $50 -- and it's already sold out.
Following news of the super-fast duplicate of the KKW Beauty founder's dress closely, popular Instagram account diet_prada pointed out that the model, Yodit Yemane -- who is wearing the replica -- leaked photos of herself modeling the look a few hours before it went for sale on their site under the label "Kim dress."
However, it was later posted on the site as the "Winning Beauty Cut Out Gown."
On Instagram, diet_prada asked the question: "Did Fashion Nova whip up the dress overnight in their Los Angeles atelier after seeing Kim in it or is she peddling her vintage finds to mass retailers ahead of debuting them for a calculated, timely release?"

"It’s devastating to see these fashion companies rip off designs that have taken the blood, sweat and tears of true designers who have put their all into their own original ideas."
The rant continues with a series of tweets, where one addresses her vintage Mugler dress directly.
"Only two days ago, I was privileged enough to wear a one-of-a-kind vintage Mugler dress and in less than 24 hours it was knocked off and thrown up on a site - but it's not for sale. You have to sign up for a waitlist because the dress hasn’t even been made to sell yet."
"So, as always, don’t believe everything you read and see online," Kardashian said in another tweet. "I don’t have any relationships with these sites. I’m not leaking my looks to anyone, and I don’t support what these companies are doing."
This isn't the first time Kardashian has called out fast-fashion retailers for copying her style. Earlier this month, she posted a photo of herself in a fitted gold dress from her husband Kanye West along with a caption that included, "P.S. fast fashion brands, can you please wait until I wear this in real life before you knock it off?"
Coincidentally, diet_prada caught this too and posted a side-by-side photo of Kardashian in her gold dress next to a post from fashion retailer Missguided of a model in a look that was almost identical and noted to be dropping online in a few days.
Kardashian's style has had an influence on many of her fans, and now, retailers seem just as impacted by her fashion choices.
