Cheap Logo Designers

I watched this American channel “style” channel and there the programs ” worst and the best of 2008″ and they said as wearing a true logo shirt is cheap. Some host I don’t know his name said “if you have money you don’t need to show up wearing a shirt showing up the name of the designer”. So now I was wondering if he said that, thus mean wearing logo isn’t good choose.
I live in Toronto and as you know it’s one of cities of fashion, so I’m thinking of going and buying some of logo shirt, but now I even don’t know what to do.
