I have never worn the ones pictured above. some might say it's a fashion mistake. But I think it is really up to you & whether it fits your personality. I have worn a bracelet from The CompassionateFriends.org in memory of my sister for 3 1/2 years. It fell off while I was attending an event and I am going to get a replacement.

I wore one that supported Cancer until it got caught on something and tore. I think it is all a personal preference. I personally don't mind them, but others might think they are gaudy.
