Khloe Kardashian has been accused of stealing designs. The evidence is pretty damning.

A fashion designer has accused Khloe Kardashian of ripping off her designs for the reality star’s label Good American – and the evidence she’s provided to lawyers is pretty damning.

Last week, Destiney Bleu – who has designed for stars like Beyoncé, Serena Williams, and Lady Gaga – made the accusations on Twitter, posting a campaign video by Kardashian’s brand.

The video featured glitter bodysuits that look remarkably similar to some of Bleu’s designs for her label dbleudazzled.

However, the youngest Kardashian sister replied to the allegations on Good American's Instagram, posting three images of Cher, Diana Ross, and Britney Spears in bedazzled bodysuits - stating these were the inspiration, not Bleu's designs.

"Important to know your fashion history #nofrauds," she wrote next to the image of Cher.

Followers weren't convinced, however, with many sharing their scepticism. One wrote, "I see you are setting up your defence argument."

The denim company then released a statement saying "under no circumstances did Good American or Khloé Kardashian infringe on another brand’s intellectual property and we are going through the proper legal channels to handle the situation."

That legal channel the company was referring to was sending Bleu a cease and desist letter for defamation of character, People magazine reports.

The letter asked Bleu to stop making "false statements" and to stop her "trolls" from attacking Khloe Kardashian.

But instead of apologising or retracting her statement, Bleu's lawyers lodged a legal document providing a timeline that she says points out exactly how the designs were stolen.

As Kim Kardashian might put it, she was showing her the receipts. In this case, literally.

Blue's timeline, reported by People, shows screenshots of email exchanges between her and Khloe's then-stylist Monica Rose and the invoice that Bleu sent her for customised jewelled underwear.

The timeline published by People shows in November and December 2016 Khloe ordered 14 items from dbleudazzled. Days later, her stylist Monica Rose asked to borrow two bodysuits in black and nude -and it's these designs that Bleu claims were copied.

Later, the fashion designer invoiced Khloe for the body suits, as the 32-year-old had wanted to keep them.

Receipts aside - it's the letter that accompanied the timeline wear Bleu makes her strongest argument.

"Destiney has a Constitutionally-protected right to inform others that Khloé Kardashian has copied her designs. She will not silently abdicate that right in response to a frivolous, two-bit email from you threatening legal action," it read.

"If Khloé wants to continue stealing designs from indie creators and mass produce them with no credit, then Khloé will rightly face judgment in the court of public opinion."

The letter goes on to say that Good American's statement's wording - insisting it did not 'infringe on another brand’s intellectual property' - was a tricky move.

"Of course, she didn’t – copying clothing and fashion is generally not intellectual property infringement. It is not illegal for Khloé to copy Destiney’s designs—it is just tacky, disrespectful, and in bad taste."

"... You should be ashamed."

And just when you think the feud couldn't get any nastier, Good American told People that Bleu's accusations were "flagrantly false" and "little more than a cheap publicity stunt and an attempt by Ms Bleu to get her 15 minutes of fame".

Kardashian's camp also maintains that Good American design team "had never heard of Ms Bleu or seen her designs".

What do you think of the Kardashian vs Bleu legal feud?
