Hand-me-downs

In the first movie, Draco Malfoy says to Ron “Red hair and a hand-me-down robe? You must be a Weasley.” This detail is carried over visually to the second film very well. In Harry Potter and the Chamber of Secrets, Ron’s robes are older than everyone else’s, as they are hand-me-downs. The Weasleys win a sizeable amount of money in the lottery over the summer between second and the third movie and sure enough, his robes don't look too dingy in the third movie.
