How do you approach a woman without looking like a creep or making her feel randomly uncomfortable?

I go to university and there's a lot of women there and I want to talk to one and hopefully develop a friendship that becomes a relationship and we get to have some fun times with each other, my fear is that I'm 5'4 ft tall and 120 pounds and I'm white and living in the United states I get the impression that guys who look like me don't fit the Western male beauty standard (being tall and über muscular and having an aggressive personality and being dark skinned), I have aspergers but I know how to have a conversation with anyone but I have this feeling in the back of my mind that they will not have any interest in wanting to interact or communicate with me and all I would do is introduce myself and if she's alone sitting somewhere I'd ask if a seat next her is taken and I'd she says no then I'll initiate a conversation and ask about her experience at college and keep it vanilla and if we vibe then I'll ask for her number and see if she gives it to me and we hang out.
