Graphics are misaligned and fuzzy in areas

I don't see a place to upload a supporting photo to show the example. But I ordered a shirt with custom graphics I made. I supplied a 720dpi image at scale. I did test prints on my end and everything was crisp. But when I got my shirt there are areas where things didn't line up, and edges were fuzzy. The artwork was not this way, so I'm not sure what happened in the production process.
