Party on! The contestants are split into two teams of three in the sixth "Top Design" challenge and asked to design competing party spaces for Bacardi Limon to entertain guests of ELLE DECOR Magazine. Joining host Todd Oldham are judges Jonathan Adler, Margaret Russell and Kelly Wearstler, who - along with event producer and special guest judge Ben Bourgeois - will decide who has created the "Top Design," and who will be sent home.
