Part one of American Idol's season finale aired last night, and finalist Lauren Alaina performed not one, but three songs—requiring three outfit changes! For her second number, Pam Tillis' "Maybe It Was Memphis," Alaina chose a girly tutu dress from Mint Collection paired with boots by 1883. She accessorized with a Dolly Parton necklace and a ring and earrings from Bijou Tresor. Click though the gallery to see all three of her looks! The final episode of American Idol airs tonight at 8 p.m. Eastern Standard Time on Fox, and U2's Bono and the Edge are slated to perform. Tell us, who are you voting for: Lauren Alaina or Scotty McCreery?
