Harry Potter Cosplay: Professor Sibill Trelawney Trelawney is definitely one of the favorite background characters of Harry Potter for ...

Emma Thompson

Day 7: Least favorite Hogwarts professor. My first thought for this category was Umbridge, but she only had a year of teaching so I decided to go with Trelawney who was a bit more regular than Umbridge. It always annoyed me that even though Trelawney was an actual seer, she couldn't control when she had her visions. So when she couldn't channel her powers of divination, she would make up a prophecy and use it to terrify the students she had. In many ways she was just like a bully.

Professor Trelawney costume is patchwork clothes in earthy tones and she is very partial to shawls. For most of the movies, she wears a tunic, maxi skirt, bandanna headband, and big round glasses.
