A senior at Cornell University caused a stir when she started to undress during her thesis presentation, saying it was part of making a stand for those “who have been asked to question ourselves, specifically our appearance for the comfort of others.”

Letitia Chai live streamed the presentation after what the student newspaper described as a “clash” with her professor after a trial.

Speaking to the Cornell Daily Sun, Chai said that she was shocked when the professor, who is a woman, questioned the shorts she was wearing. The discussion escalated until, the paper reported, a male student in the class told Chai that she had a “moral obligation” to dress conservatively. Chai then left the room.
