Anyone can wear a leather jacket. I wear leather jackets. (Technically pleather) usually I wear a hoodie underneath my leather jacket. You get the badassery of a leather jacket and the warmth and comfort of a hoodie plus you get twice the pockets.
In my POV I think anyone Whose confident in themselves can pull off a leather jacket, for example my uncle is in his early 40s, keeps in shape and lools great in his jacket! Then again my little brother (12) can pull off the adorable cutie look. Final example; my boyfriend also pulls off a leather jacket look with glasses and tossled hair, it's not really about how "hot" you look (Altho that never hurts) believe in yourself, work for it, BOOM anyone can pull off anything. Hope that helped>
