Fanning, 22, owned the red carpet at the Brimstone premiere in a floor-length, sequin-covered Miu Miu gown. The eye-catching frock shimmered blue, green and purple as the cameras flashed. Fanning’s styling included Neil Lane rings and a half-up hairstyle.

“?Mermaid Magic?#nevertakingthisoff #venicefilmfestival #brimstone,” Fanning captioned a picture of her look on Instagram.

“Strokin the tail @miumiu @neillanejewelry,” Fanning wrote for a video she uploaded on the social media site.

Fanning’s last snap showed that some of the sequins had fallen off and landed on her leg. “I became one with the dress. #mermaid,” the actress wrote.

In Brimstone, Fanning plays a frontierswoman who is wrongly accused of a crime, and then becomes a fugitive. Kit Harrington and Paul Anderson costar in the film. It’s slated for release Oct. 13.
