I wear soccer jerseys to work (I work in finance!) and no one says anything. Everupme else wears a shirt or suit, but hey I'm smarter than them I'm always the one fixing their f*** ups.
Liverpool missed a trick, they arent as marketing-mad as man ure, Real Madrid or Barcelona. There is a lot of money to be made, but the team (like Madrid and Barca) are about winning and any profit goes into the team usually. man ure profits go to Malcolm Glazer, owner of Tampa Bay Buccaneers... it's all about making money for them, not love of the game. Even Chelsea (who are accused of buying success) are not making a profit but trying to make a successful team. Arsenal are similar too, they play great football though. This year the best to watch has been Barcelona though. How can you not admire Ronaldinho, Eto'o, Messi, Deco and co ? I have a Barca shirt I got in their stadium with my name on it (in 2001), as well as recent ones like Ronaldinho and Deco. The only English team shirt I have is one England national team, and a bunch of Liverpool shirts - the quality of recent years' Reebok Liverpool shirts used far superior materia that felt like good quality comparedl to the paper-like Nike ones
Unless you get a Nike jersey from South America, I had some Boca Juniors shirts shipped from Argentina, much better quality!
