Harry Potter marauder's map to shirt

Harry Potter marauder's map t-shirt purchased at Universal studios Wizarding world! In the sun light, little foot prints appear on the shirt. I am so sad this shrank in the wash, it fits more like a woman xs or junior s now. This is marked children's small, but had an oversized fit so originally I could wear it comfortably ( I'm typically a woman's small) Tagged hot topic for exposure.
