Socialite-turned-designer Ivanka Trump is facing legal action from fashion mogul Derek Lam over allegations she copied one of his creations.
Donald Trump's daughter received a cease-and-desist letter from Lam demanding she withdraw her $150 (£93.75) Cadie wedge shoe from the Ivanka Trump Footwear Collection.
The document suggests the shoe is a copy of Lam's $780 (£487.50) Ayami design, and Jan-Hendrik Schlottmann, chief executive officer of Derek Lam, tells Women's Wear Daily, "We have seen very similar copies before but we have never seen a shoe that perfectly copied."
However, officials at the distribution company behind Trump's collection, Marc Fisher Footwear, have refuted the claims.
A statement from the firm reads, "The Lam wedge sandals are of a popular design type that has been used by numerous manufacturers for many decades. There is nothing iconic about the appearance of the Lam sandal. The Ivanka Trump sandals prominently display the Ivanka Trump name, and there can be no confusion as to the source of the Ivanka Trump sandals."
