Gucci has reportedly filed multiple cease-and-desist letters to Forever 21 following apparent copyright infringement on a number of the fast fashion retailer's items.

According to Fashionista, Gucci sent the first of these letters as early as December 2016, which demanded that Forever 21 pull all items featuring "any and all use of" blue-red-blue stripes. A second followed in January and a third in February, both of which expanded the complaint to not just the blue-red-blue stripes but green-red-green stripes as well. Gucci stated that the stripes are "confusingly similar" to those of its own.

Far from rolling over however, Fashionista also reports that Forever 21 is now seeking legal protection against the threat. The fast fashion retailer filed a legal complaint on Monday.

"Forever 21 is not infringing any Gucci trademark," states the case document. "Gucci's trademark registrations relevant to this dispute should be canceled. Gucci's pending applications should not proceed to registration. This matter is ripe for a declaratory judgment."

The irony in all of this is that Gucci has itself been accused of plagiarism in the last few weeks — first of copying designs from legendary Harlem courtier Dapper Dan, and then by two other separate designers.

Forever 21 is also no stranger to disputes over plagiarism. In the last year alone it has been accused of ripping off Kanye West, Thrasher and Emily Oberg. Stay tuned for more information on this one.
