Night Owl and windbourne, I'm not sure we know enough of the context to judge the teacher. Based on my own personal experience with a few teachers (as well as the experiences of others), Night Owl might definitely be right. I've seen some tactless, even mean, teachers who seemingly want to hurt their students. Not many, thankfully, but enough for me to entertain the possibility that this teacher's behavior might be totally inappropriate. On the other hand, a fair number of students don't know how to dress; some do wear stuff that's too tight and revealing. It's hard to tell from the photo, but it is perfectly conceivable to me that she might have experienced a wardrobe malfunction. And some girls (and women) don't dress appropriately for a professional context. What if this student had asked about a job or an internship? In that case, some gentle remarks might have been in order. I'm with John 500AF: this is not a Facebook issue. Before we judge, we should hear the teacher's side.
