18-year-old Malia Obama looked grown-up and sophisticated at the presidential farewell address on Tuesday night. Malia wore a simple black choker with a black and white color-blocked dress. At the end of his address, President Obama tearfully thanked Michelle Obama for her role as First Lady, and that's when the cameras cut to Michelle and Malia, wiping away her tears. If you want to copycat Malia's look, her dress is still available online.
