'Tis the season for spooks, spells, and shiny, mesmerizing manicures. Just ask Jessica Simpson, whose prismatic silver set is like magic in a mani.

Simpson stepped out to attend the premiere of Ryan Murphy's new legal drama All's Fair and set the mood for spooky season in a smoky gray set with a cat-eye effect that made it shift and sparkle in the light. Her nails were long and filed into a soft almond shape, then painted a cool gunmetal gray shade with a microfine shimmer in a lighter silver tone. In certain light, the magnetic cat-eye texture made them look almost white, while from other angles, they were a deep, dark gray reminiscent of a mystical twilight sky in October—or maybe even the “dark side of the moon?” The sparkle factor changed as she moved too, looking fully matte one moment and blindingly glittery the next. A handful of diamond rings added even more shimmer and complemented the luminous silver tone of her nails.

Cat-eye nails have been one of 2025's most prevalent nail art trends because they're beautiful, unique, and customizable. “It creates a sense of mystery and versatility, as the color appears to change, making it both bold and adaptable,” Jacqueline Pham, a New York City-based nail artist, previously told Allure. They can be soft and pearly, textured with 3D elements, or paired with a French tip—and that's just for starters! We've seen them on nail trendsetters like Vanessa Hudgens, Lindsay Lohan, and Cardi B, and now, Simpson herself! We know she loves a nail art moment; in July, she hit the Today show stage with all ten fingers covered in intricate, Western-inspired designs. If you're looking for a mani that sets the tone for spooky season while still feeling glamorous and luxurious, why not follow Simpson's lead and lean into the mystical, magical texture of a cat-eye nail?
