Also, how would someone wearing blue jeans (and a t-shirt) be seen to someone from the 40s, and would that imply anything about his social status as well? (From basic googling I get the impression that soldiers returning from WWII wore jeans fairly frequently, but I don't know if that means someone would assume someone wearing those would be a soldier, or working class, or what.)
Background: my character has just been sent back in time from ~2010 to New York around 1946 or 47. He's a white kid (about 19) wearing jeans and a t-shirt and has a pretty typical New Jersey accent. I'm trying to figure out what my main character's first impressions will be upon finding him. If you can think of anything else that would seem 'off' about someone from the future in that time period, I'd appreciate that as well.
