Upcycled clothes enter into a grey area in the legal world. You don’t want to infringe on copyrighted material like original artwork, designs, lyrics, and quotes. Or on trademarks, like company and product names, and brand identity, like logos and slogans. However, fair use is allowed. This is where you can use and build upon existing works to create new works. But this is tricky to argue with in a legal matter, as it’s quite broad. Avoid using copyrighted imagery, sayings, and specific logos and brand names when reselling. Seek legal counsel if you’re unsure whether your upcycled clothing violates copyright or trademark law.
