However,I didn't watch the video.
I think places like schools should be neutral and people dressing sexy is distraction from learning .

And this goes for teachers too , as in if your students can't wear a short mini skirt you should not be wearing a blouse that shows too much.
I'm done with my soapbox speech you can all go back to your former programs
