It's all about bold colors, tribal patterns and edgy metallics as designer and event planner Dina Manzo takes on double challenge of decorating the first home of The Biggest Loser contestants, Alexandra and Antoine, and then throwing them an engagement party in their new space. Dina carefully blends the rich colors and glamorous details Alexandra loves with the comfortable and casual feel Antoine is used to to give the couple a home where they can live and entertain. When the space is complete, it's the perfect backdrop for a joyous open house-style party to celebrate the couple with good drinks and a mouthwatering spread of healthy party food.
