If Catherine, the Duchess of Cambridge (that's Kate Middleton, FYI), is any indication, we predict bright red will be everywhere come spring. Aside from the Catherine Walker coat she wore in New Zealand on the first leg of the royal tour, Kate wasn't the only one sporting red this weekend. Shailene Woodley stunned in a gorgeous Donna Karan gown at the Divergent premiere in Madrid, and Olivia Munn looked pretty in an airy red dress at the American Country Music Awards.
