Mickey Mouse© Muscle Tee (Kids) | FOREVER21 girls - 2000092019

The top you are looking for is a muscle tank with a classic Mickey Mouse from the 1930's, except I can't seem to find that one anywhere. The closest one could find was this one from Forever 21, except it features the newer version of Mickey Mouse from 1990-today. My guess would be that this might have been a vintage t-shirt with the sleeves cut off. I hope this helps!
