Rachel McAdams is fashion-forward in futuristic floor-length gown as she steals the show at About Time premiere

She's best known for her love of down-to-earth, low-key style.
But Rachel McAdams embraced futuristic fashion for the premiere of eagerly-awaited new Richard Curtis film About Time in London on Thursday night.
Stealing the show in a floor-length lavender Roksanda Ilincic gown and towering stilettos, the 34-year-old walked the red carpet at Somerset House.

Her hair, which was a slightly more fiery shade of red than usual, offset her porcelain skin, giving her an ethereal look as she posed for photographs.
The dramatic gown, which was long-sleeved and had a train which dragged along the ground, was cinched in at the waist with a perspex belt.
With jutting shoulder pads and a long blue turquoise panel down the back, the dress certainly wasn't a safe choice for the star, who clearly wanted to make an impact.

Rachel, whose ex-boyfriend Michael Sheen was recently spotted out and about with co-star Caitlin Fitzgerald, certainly seemed keen to grab the limelight as her co-stars paled in comparison at the London opening.
She was joined at the central London venue with her leading man Domhnall Gleeson, who looked dapper in a simple grey suit and navy tie.
Seeming in great spirits he laughed as the cameras snapped away, putting his arms around co-stars Bill Nighy and Margot Robbie.
