The contestants are asked to design a "Garden Party" dress. The morning of the challenge Tim Gunn takes them on a field trip to Manhattan's Flower District where they discover they must construct their garments using plants and flowers. They are given an hour to shop and then return to the workroom to begin the painstaking work of making their dresses. Racing against the clock, the designers create an array of stunning work, making it a difficult decision for the judges on the runway. Still, one designer comes out on top and one is sent home, but just barely.
