The 36-year-old actress turned heads in a daring strapless look by David Koma that featured off-the-shoulder long sleeves that descended into gloves with crystal-embellished floral details. A thigh-high slit showed off Fox's toned legs and clear platform heels Andrea Wazen.
The "Transformers" actress walked the red carpet with her fiancé Machine Gun Kelly, who wore a glittery top with a spiked suit jacket and trousers by Dolce & Gabbana. The pair took couples dressing to another level, showing off their matching black and crystal looks in front of a slew of adoring fans.
Fans praised Fox's look, dubbing her a "style queen" and the "best-dressed" of the night.
"Just when you think that you cannot out-do yourself, you do!" commented a fan on Instagram. "This look absolutely slaps!"
"You are the style QUEEN! This dress slays and you're the best-dressed for sure!" wrote another.
"I love your look and I love that you matched with your man!," said another. "So chic and iconic!"
In July 2021, Fox addressed her and Kelly's tendency to wear coordinating outfits in an interview with Jimmy Kimmel.
“We do, yeah, [coordinate our outfits],” Fox said in the interview. “That’s something I started with him just because he’s such a flamboyant dresser that I can’t really pull off just the sweatpants or the yoga gear anymore."
"I have to like, elevate myself to his level so whatever he’s—because he’s always covered in grommets, zippers, sequins, everything’s pink, everything’s glowing. He’s always coming off of a stage show so I have to kind of match what he’s doing so we do coordinate often," she added.
