Shailene Woodley Heats Up 'Insurgent' Red Carpet

Shailene Woodley swapped her usual bohemian style for an elegant white gown at the Insurgent world premiere held at the Odeon cinema in London's Leicester Square on Wednesday night. The 23-year-old actress wore a classic Ralph Lauren Collection evening dress (Silk Alexandria Gown, $7495) which featured a macramé design at the shoulders with a daring, backless cut-out.

The Divergent sequel hits theaters on March 20.
