The designers are awakened by a surprise visitor who may or may not have arrived by chimney. Tis the season for holiday parties and the designers will be challenged to show their sense of spirit in the perfect party dress. They quickly learn that this isn't a conventional holiday affair… it's the unconventional materials challenge! Channeling their own holiday memories, the designers have two days to transform a winter wonderland into a wearable wonder, and then it's up to the judges to decide who's been naughty or nice.
