I couldn't run in the sun with shorts on, if it was below 60!. My legs, esp. my knees get freezing. I can wear capris for running down to about 48, but below that, it's tights. I am often amazed at runners who can wear shorts when it's 38, like I saw this morning. While I am better at not overdressing on the top half for running, my knees need to be covered. If it's raining and cold, I want to be covered or I'll be shivering. Sleeveless and arm warmers? Yikes! I must be a wuss.
