What should I do about a coworker who always stares at me. ?

I catch my female coworker staring at me multiple times a day. Even when I dont look, I can feel her looking at me. I thought it was because I was new and she was maybe keeping an eye on me but 5 months later and she's still doing it. Today she told me the pants I was wearing are my Friday pants because I apparently wear them every Friday. Shes just weirding me out and I'm at the point where I feel like im going to snap and I dont want to do that but it makes me extremely uncomfortable.  I just dont know what to say to her or maybe HR?
(Shes 20 years older than me so I know its not a crush or anything. I do know that shes VERY nosey though so I think that's part of it)

Ask her what her problem is, why is she constantly watching you? Confront her, ask her to go bother some3one else. she does this because people let her, and say nothing.  If she keeps doing it, go to your boss or HR.
