Designer Derek Lam is alleging that Ivanka Trump has stolen his design for a pair of wedge sandals that are part of her footwear line.
The designers legal team sent Trump's company, Ivanka Trump Footwear, and the collection's distributor, Marc Fisher Footwear, a cease-and-desist letter demanding that the remove the shoes from stores within the next seven days, according to WWD.
Lam claims that Trump's Cadie wedge sandals (which sell for $150) are too similar to his Ayami wedge sandals (priced at $780).
Derek Lam CEO Jan-Hendrik Schlottmann told WWD that one of the company's shoe designers spotted Trump's sandals on bloomingdales.com.
“We have seen very similar copies before but we have never seen a shoe that perfectly copied,” Schlottmann said. “It’s such an investment to make a shoe. … We had to protest this.”
He added that he ordered a pair of the Trump-designed shoes and noted that they don't appear on her own website.
“I’m sure Ms. Trump doesn’t know her wedge is copy because it’s through a license," he said.
Marc Fisher Footwear denied the claims.
“The Lam wedge sandals are of a popular design type that has been used by numerous manufacturers for many decades,” the company told People in a statement. “There is nothing iconic about the appearance of the Lam sandal.”
Trump -- who stars alongside her father, Donald Trump, and brother, Donald Trump Jr., on NBC's The Celebrity Apprentice -- also designs a line of jewelry and handbags.
