Ron Weasley, who has presumably never watched an NCAA sporting event in his life, wearing what appears to be a Colorado Buffaloes hoodie converted into a sport coat — at a movie premiere. With what appear to be overlarge tearaway pants and skechers.

Where did he get this?
Who made it?
Why did they make?
Why did he choose to wear it?
What did he think it meant?
Are there other team hoodie/sport coats available?
