New from Sephora, we are excited about OPI’s Just A Little Dangerous nail color ($9), which is an opaque metallic amethyst. As the name suggests, this is a dark, mysterious wine shade with an attitude. You’ll be happy to know that this is part of fall’s hottest trend—edgy neutrals with a twist. Inspired by the iconic pure-rock vibe—empowered, impassioned, and defined by the music—this sexy hue is tough and alluring, leather and lace. The long-lasting, chip-resistant polish ensures flawless results with each application, and its green ingredient list excludes DBP, toluene, and formaldehyde.
