Clothing Can't find a shirt!

[koopasta]

So, I had an old QR design saved onto my phone, and when I realize that I want it most, it's gone. I've tried looking absolutely everywhere and it's nowhere to be seen. I can't remember everything, but it was a black, short-sleeved shirt. The front had a picture of Marina from Splatoon 2 on it, and the back of it had her octopus form. I want to use this shirt again, but unfortunately I can't find it after a few hours of searching. If anyone has/knows where to find this shirt, please tell me!
