Close up, this particular shade of rich brown is nuanced enough to stand alone, without a shimmer topper or any chrome powder. If you’re looking for the perfect polish, you’d find it in Chanel’s Impulsion, a brand-new shade from the fall-winter collection. Goldstein used two thin layers of it, plus a gel top coat (also by Chanel) for shine and longevity. Goldstein used a brown polish for Julia Garner’s Emmy’s manicure, too. This one, Chanel’s Essentiel, reads more milk chocolate. If you happen to have multiple shades of brown, you can throw them in a gradient manicure, like this.
