The lawsuit, filed in Manhattan federal court, accused Trump and her manufacturer of copying Aquazzura's "Wild Thing" design for her Hettie shoe.
Celebrities like Olivia Palermo and Solange Knowles have been "parading the red carpet" in the Aquazzura footwear, according to a fashion article cited in court papers.
The company accuses Trump of "seeking the same success...but without having to put in the hard creative work."
The lawsuit says Trump "copied nearly every detail" of the coveted Wild Thing shoe "from the shape and silhouette to the fringe covering the toes, to the tassel on the heel."
The difference? Trump's version sells for a fraction of the price.
