MERRY CHRISTMAS and HAPPY HOLIDAYS! Cascalote Elementary School is holding its first Annual Festive Fashion Show. Designers from all around the world are competing for the grand prize, which includes a trip to New York Fashion Week where the winner's design will be featured. Gabriella has decided to enter. A week before the show, the designers arrive for rehearsal to find a key piece of their best designs have been stolen. The designers are all accusing each other of the theft. Gabriella is no exception. Is Gabriella the thief herself, or can Stormy and Cassie find out who the thief is and clear Gabriella's name?
