Theo James and Shailene Woodley definitely know how to command a red carpet. Case in point? The duo's killer ensembles at tonight's world premiere of their film Insurgent in London.

At the event, James—sporting some handsome new facial hair—chose a dapper navy blue Dolce & Gabbana three-piece suit that had us swooning. But Woodley's gown is what made our jaws drop: The actress glowed in an ivory Ralph Lauren Collection frock with an open back, which included over 100 hand-made strips of silk cream organza applied over a layer of silk tulle. To top off her winning look, the boho beauty added several delicate feathers to her pinned-back hairdo that were the perfect finishing touch.
