I’m a graphic designer and I do a lot of freelance work, like designing logos and shirts for clients from other countries. While I was browsing through Instagram, I found one of my designs printed on a shirt and I don’t remember working for the clothing line that posted it. I did some research and I found out it was a foreign brand from Europe that stole my design. What sort of legal action can I take for the design they stole from me? Is it going to cost a lot to hire a lawyer to help me out with this issue? Anyone who has ever had their work stolen and used without compensation or permission knows how badly it feels. However, if it’s too costly I’m afraid I’m just gonna have to let this one slide. Any advice would be great.
