I'm 6'2 165 small shoulders?!

I don't know if I look alright, my friends are no help they're too nice. My wrists are small along with my shoulders which I am really self conscious about. What should I do to get bigger, like what workouts? Should I even try or would that look stupid being a muscular guy with small wrists and shoulders? I just kinda want to know what to do and if Being tall and thin is remotely okay?
