So this seems like it has to have been brought up before especially with the artists at least. The pictures used to model the tee do not even come close to what the actual shirt ends up looking like. I've gotten shirts that I was iffy about but when I received it in the mail it looked so much better. My cousin has shirts that I passed on but look completely different than the picture on the website.
Conversely, shirts like Senzu: Energy Bean by ValHolla ended up looking way bigger than the mock-up. At the very least, TeeFury keeps us on our toes.
