For the London premiere, which had a fitting blue carpet, Heard stepped out wearing a Valentino gown with a coordinating bonnet in the same fabric - or, if you're a sea queen, who may soon rule the underwater kingdom of Atlantis, it's almost certainly a couture swimming cap.
The green-and-gold-foil floral gown features a plunging square neckline and Empire waist with a cutout back, thigh-high split and a wide, trailing skirt. Heard opted to finish the look with gold Brian Atwood platform heels.
Pick pretty much any other person to wear this look and it's a disaster waiting to happen. Heard, however, pulls it off spectacularly and leaves us not only wishing we owned her face, but also a couture bathing cap to go with it.
