I'm a skinny girl. How to get used to showing my body more?

Don't get me wrong, I love my body. I'm not ashamed of it but I do feel self conscious around others. So much so that in public at least, I don't wear shorts. I don't wear skirts or dresses. Nothing that shows my legs. It's become more and more a habit for me, summer after summer, to wear pants and suffer. I thought for awhile that maybe I'm just not a girly girl, but I think it's more so about what others must think and I shy away from more revealing clothing. So how to just be more confident is more what I'm saying?? I'm five foot two and maybe ninety pounds
