Die-hard Harry Potter fans probably think they've spotted every little detail in both the books and films—if not, they've certainly tried. But with each new viewing, fresh discoveries pop up, including subtle things you may not have realized were intentionally included. For instance, did you notice that after Harry Potter and the Chamber of Secrets, Hogwarts students practically ditched their robes in favor of everyday Muggle clothing? That wasn’t by accident.
In the first two films, the Hogwarts uniform was a big deal, and the students were almost always seen in their robes. However, in 2004’s Harry Potter and the Prisoner of Azkaban, robes were hardly ever worn outside the classroom. This shift in style came from costume designer Jany Temime, who worked on the last six films and had a unique vision for how the characters should appear.
“I wanted them to look like normal kids, not like they were in a costume,” Temime told InStyle in 2017. “I wanted the story to feel real, like Harry Potter wasn’t just something you read in bed but something tangible. Because at the end of the day, they’re all teenagers from broken homes, living together in a boarding school, and each of them has a special gift.”
In the third film, the students started to show signs of growing up, which explains why they would tire of their childhood robes and seek to express themselves through their clothing. So yes, they embraced Muggle fashion. But more than that, they dressed like the teenagers they were becoming.
