The three remaining designers compete in the finale for a chance to win a life-altering grand prize! However, because this is All Stars, the final three designers only get four days and an hour and a half at Mood, to complete a full mini collection. With the help of previously eliminated designers, the final three duke it out and give it all they've got to prove who Project Runway's true All Star is.
