Hi there! First and foremost, what is platonic? I mean how do you define platonic in your case? Analyze yourself. the feelings you have for her. Anf from thereon, we will know. And also, you should also know if those actions were already manifested even before the two of you have met. Is it already her habit of doing such things or is it just recently after the two of you have met. Because if that is the latter, then it is indeed clear that she is somewhat really into you or seducing you. And you must also know that there types of people like that. Persons of that kind who seduces are also called HISTRIONIC Type of persons. They are persons who are somewhat attention-seekers whose only way to catch your attention is to dressed in such a way and seduces you. What I am trying to say here is you should try to atleast analyze it if is natural on her part to act or behave that way or is she really doing it with the clear intentions of catching your attention.
