I have a Livestrong one which my mum got for me off a friend of hers at her work, he bought a box from America and sold them at school to raise money for the charity. I also have one that says UNITE and some other stuff on it (in another language), which is suposedly a Tsunami one, but my sister bought it and doesnt wear it so I thought I would, I wear the livestrong one because I recognise the charity I am supporting and the money is going to a good cause, not to look cool. It's rediculous how this has become what it is, with everyone wearing them just to look cool. The only other ones I would wear are the Racism in football one, Make Poverty Historry, the Radio 1 Anti-Bullying one (as I was bullied for 11 years at school) and the Breast Cancer one. But then If I had all them people would be like oh look at you trying to fit in, they dont realise that I personally would wear them to support the people who suffer poverty, bullying, or racism. But I can't be bothered to go and buy them because of the persona built around them these days.
