I have a 1994 German shirt that is for of all people, Klinsmann, I need to get that shirt out, it's probably one size to small to wear. I got it about 6 years ago in a thrift store and even at that time, I considered it a bargain. Goes without saying, I don't really cheer the German team, they are okay and have had some very good players and teams.
Italy might not have had a "loud" jersey/shirt but per the USA's jersey above with stars and Germanys, USA 1994 was the World Cup of a few teams wearing dynamic kits/uniforms. Cameroon's I'll just link it, image is too big.
