My uniform of the day, most days is a t-shirt. Love the simplicity, feel, utility, and price! I get a lot of shirts at thrift shops for around two dollars most days. So I find it real hard to pay 12, 20 dollars or more for the same thing, only newer perhaps. I recently bought some white shirts with the idea that they would be great for summer wear, and be very visible while riding the bike. But white is plain white, and I decided to "spiff" up a couple of shirts. I came up with the ideas presented here, and am happy with the result.

I think the simple designs make a world of difference!
