Julianne Moore wore a manicure in a shade called Dark Bordeaux at the BFI's 70th London Film Festival, pairing short, rounded square nails with a glossy top coat. Sue Carroll, founder of Young LDN in Notting Hill, described the color as bordering on black in certain lighting: "Rather than a traditional red-toned burgundy, this darker bordeaux shade is more expensive and refined."
Carroll said the glossy top coat matters for the look, explaining it "catches the light and allows those beautiful wine undertones to come through, rather than making the color look flat." She recommended pushing back cuticles, buffing nails and applying two thin coats rather than thick ones for a smoother finish, and noted darker polishes show chips and uneven edges more easily, so careful prep matters. Carroll added that Bordeaux shades vary from purple-leaning to warmer brown or red undertones, so those worried about intensity can opt for a berry-toned version or keep nails shorter, according to Harper's Bazaar.
