Yes, I also noticed that Harry wore the same shirt in the first 3 movies, didn't you? In the 4th and 5th movies he took off his shirt, but in the 6th Harry put on his one againxD
... That is so, so awesome. I love how people's faces develope & change over time. Find it sorta fascinating The kids in the Potter movies are no exception. I love how oversized the shirt is on young-Harry :'D
The change is verry cute! Thx!
