Jessica Chastain Interstellar Premiere - P 2014

The 'Interstellar' actress channels Old Hollywood glam in a dazzling pink gown

The Dress: A dusty rose Saint Laurent gown featuring a single shoulder strap and asymmetrical cutout.

The Wearer: Jessica Chastain

The Event: The London premiere of Interstellar at the Odeon Leicester Square on Wednesday night. 

Why We Dig: Chastain stole the show in an elegant pleated gown with an embellished, crystal-covered strap — outshining even co-star Matthew McConaughey, who, by the way, arrived at the premiere in a plaid suit. Wearing diamond Chanel studs and a sleek low bun, Chastain was the epitome of Old Hollywood glamour. The 37-year-old completed the look with a simple cat eye and bubblegum-pink lips, reminding us all of why she's earned her style-star status.
