This is one of the shirts that Robin Williams wears as "Andrew". He is seen wearing this as he approaches the baseball field to talk with the NDR-116. However there is a continuity flaw in filming because when he is standing next to the other NDR, the shirt is different with a copper colored zipper, larger zipper pull, and pockets on the shirt. You can see in the second screen capture that the zipper pull matches this shirt, but in the third and fourth pictures it is a slightly different shirt.
