The 'Single Ladies' hitmaker had posed in a pair of studded leggings in the advertising campaign to promote the new line which she designed with mother Tina Knowles, but E-Label claims that it is a "copy and paste" of their creation, reported Daily Mail online.
Helba Hallgrimsdottir, who co-owns the brand, claims that Beyonce purchased their trademark 'Heavy Metal' leggings from their London store in November last year.
"I didn't understand straight away that this was her own label. I just thought she was wearing our leggings. It is practically just copy-paste," said Hallgrimsdottir.
E-label has not yet decided whether there is a case for legal action. "No decision has yet been taken. We need to inspect her brand's trousers closer because, according to law, it is not copied if a certain number of things have been changed from the original design," she said.
She added that though E-label's design was not copyrighted, the media coverage of the singer's shopping trip was likely to be adequate evidence to prove the design had been plagiarised.
