Just to add my $0.02:

The last picture in Vicki's post (the undershirt) - this type of undershirt is colloquially and vulgarly known as a "wife-beater". The stereotype of wife-beating husbands has them wearing this type of sleeveless undershirt.

Other men might wear a short-sleeved undershirt.

I remember back in the day when I went to England and I tried calling information on the phone - they could not understand me as one of the letters I was trying to say was "Z" - I pronounced it "zee" and the British used "zed".
