Amber Heards red carpet look went swimmingly with the theme of her new movie, Aquaman.

The actress showed up to the films world premiere in London on Monday in a stunning green and gold gown from Valentino Haute Coutures Autumn/Winter 2018/2019 collection. It looked like it belonged under the sea, shimmering on the scales of a mermaids tail.

The actress completed her fantastical look with a cap by Pierpaolo Piccioli for Valentino that wouldve looked right at home on a couture synchronized swimmer.

Heard added a single earring and gold Brian Atwood platform heels for an additional splash of glamour and drama to her outfit.
