TV Fashion: From 'Happy Endings' To 'The Voice,' Best And Worst Dressed Of The Week (PHOTOS)

"The Voice" kicked off live shows, with host Christina Aguilera appearing in a stunning, curve-hugging dress. That wasn't the only fashion "do" of the week: The nostalgic "One Tree Hill" series finale saw Haley and Brooke clad in trendy sweaters and necklaces and Amanda looked quite angelic in white on "GCB," a far cry from last week.

Unfortunately, some of our other TV favorites didn't fare quite as well. Karen (Katharine McPhee) pranced around in a green bodysuit for an orange juice commercial on "Smash," while "Happy Endings" put Jane (Eliza Coupe) in a mustard-colored suit for one epic wedding.
