We're officially calling it: Fall 2025 is the season of the cat-eye nail. The shape-shifting, ever-changing manicure style has taken over the tips of so many of our fave nail trendsetters, including one Ms. Hailey Rhode Baldwin Bieber, who showed off an autumnal brown cat-eye mani at the Academy Museum Gala in Los Angeles.

Though Bieber has been sticking to a very neutral nail as of late, she switched it up for the glamorous gala, which she attended alongside her BFF and fellow model Kendall Jenner. To sculpt the fall-ready nails, Bieber turned to her go-to nail artist Zola Ganzorigt, who crafted a color-changing manicure that beautifully complemented Bieber's strapless brown silk Schiaparelli gown and shifted in the light of all those camera flashbulbs.

From one angle, it looked like Bieber was wearing a simple chocolate brown manicure in the same shade as the dress, but when she turned, it was almost the exact same color as the corseted waistband of her gown, and then it shifted again, morphing into a champagne pewter hue. The beauty of a cat-eye manicure is that it toes the line between luxurious and casual. It's right at home on the red carpet, with rich color and mesmerizing finish, but it's neutral enough that you could easily wear it for a regular old workweek too. Move over, glazed donut nails! There's a new reigning trend in Tinseltown! Cat-eye nails have popped up on a plethora of celebrities, including Jessica Simpson, Cardi B, and another Ganzorigt client, Vanessa Hudgens.
