Why is it considered odd to wear long sleeves in summer, but it’s not considered odd to wear pants in summer?

People always make a big deal about the fact that I like to wear long sleeved tops in summer (to stay out of the sun). They’re always saying I must be hot, why am I wearing it, etc.

But isn’t it the same concept as wearing jeans or other pants? Why do people see that as more “normal”?
