That's So Raven S01 E19 Escape Claus

"She can see the future. But she can't quite see what's coming next."

When Raven has a vision of getting a necklace for Christmas, she decides to wear it to school. It ends up falling out a window and breaking, thus leaving Chelsea, Eddie, and Raven to go to the mall and get a new one. Meanwhile, Cory gets Victor&Tanya to both pay him to wear a elf suit.
