I love that "Old Guys Who Get Fat in the Winter" jersey. I hope it's still around when I get old
And there's nothing wrong with a jersey being yellow, just something wrong with a jersey with the word LEADER on it being sold and not won.
Wear what you want, but be comfortable with your decision. I was OCP enough to get a celeste Bianchi/Campagnolo kit (jersey, shorts, socks, and gloves) to match my bike. My other jersey has tons of different Italian cheeses written on it. My way of making fun of all the jerseys I used to have to wear that had sponsors I had never even heard of. If anyone calls me a poseur, I smile and say thank you.
