Tinfoil, but make it fashion.

On Tuesday night, Dakota Johnson attended the Los Angeles premiere of her forthcoming movie “Splitsville,” dazzling in a metallic silver gown that many humorously liken to a sheet of aluminum.

The actress’ high-shine Gucci number boasted a strapless neckline and floor-sweeping hem.

Foregoing a necklace, she enhanced the sparkle with Roberto Coin jewelry, featuring dangly diamond statement earrings and a series of matching chunky bracelets.

Johnson’s red carpet beauty appearance was quite understated, with her long brunette hair styled straight and a subtle smokey eye look that accentuated her eyes.

Many fans shared their hilarious comments on the look under Check the Tag’s Instagram post.

“I’m really into her as someone cosplaying a left over tortilla in tinfoil,” one person quipped. “Honestly, she could pull off donning a roll of Reynolds’s Wrap any old day. She is stunning,” a second joked.

But not everyone is poking fun at the foil-looking gown. “I feel like a necklace is missing but beyond that, this is a great look for her,” one user wrote.

Another added, “I always love Dakota’s style. She always looks lovely and doesn’t need to be OTT. Always simple and elegant 👏🏻✨”

Johnson has been busy promoting “Splitsville,” a rom-com also starring Adria Arjona, Michael Angelo Covino and Kyle Marvin, which hit theaters on August 16.
