I took one of these pics into Gimp and adjusted the brightness and contrast. In my humble opinion, that is most definetly nipple we are seeing on her right breast - the left has a pastie, the right one must have slipped or something, 'cause it's very obvious it's a nipple when the lighting is tweaked a bit, from what I've seen. A bit of a zooming in even shows the thread design convexing over the nipple.
So, I'm changing my answer to definete nipple.
EDIT: I'm trying to post my tweaked pic, but, it's just not working out right now. I'll try again later.
