My FIL bought himself and DH matching shirts similar to that. I thought it was a gag gift, but he was dead serious. He said he thought it would be nice if they wore them to the 4th of July parade.
I can't believe they left off the Statue of Liberty.
That might imply the wearer is down with immigration. Based entirely on stereotypes and my own ignorance, I suspect that's not the type of person walking around in this fine garment on any old weekday.
