Because I do the vast majority of my riding in the summer, I have a bunch of sleeveless jerseys. To me they feel just a little cooler than those with sleeves, and it elminates that tan line on the arm, so at least I can wear a sleeveless dress without looking strange. That doesn't solve the bathing suit problem, but I don't really care about that a lot. Skin protection is more important than looks, so I put SPF 48 everywhere that gets the sun. I also have that Shimano sandal spot on my foot, but I doubt that a lot of people study the way my feet look.
