She did not listen to me and wore her wings to school.
Why did you not want her to wear them?
She has now humiliated me in front of everyone.
Whether or not she wore wings has nothing to do with you and your reaction of feeling embarrassed is unwarranted. It doesn't matter what someone else does for it does not reflect on your image.
Maybe she didn't know that people would be put off by her wings, but I feel wronged by her for it.
You are not responsible for what she does and what she wears. Worrying about this and how you think others will perceive you is misplaced. Worry about your life not other people's.
