Is it OK to have crushes on people who are not your type?

There's a classmate of mine I went to school with, but at the time, I didn't find her attractive until recently, she nice, easy going, 420 friendly, she doesn't drive too and all, but right now I'm not looking to date her because I'm on a year break from dating and I'm not too sure if she's open to date someone like me. I don't talk to her that much, and I thought about contacting her and seeing where it goes when the time is right.
