Important for decades themed spirit days working at a school. My students call anything before 2010 vintage.
I bought this shirt for casual Friday at work. Everyone loved it. I got 2, "is that the flintstones?" But almost everyone knew and it sparked up a lot of conversation. It was less than half the price of the officially branded shirt. It was fairly tall without ordering it that way (I'm 6'3") and it stayed tucked into my pants which was really nice. The only negative thing I have to say about it is it's a very uncomfortable feeling fabric(polyester I'm sure). Just wear a white cotton undershirt and it's perfect.
