NARS Night Rider is a slightly cool-toned, dark lavender with a glitter finish. It is a limited edition nail lacquer that retails for $20.00 and contains 0.5 oz.
NARS Night Rider Nail Lacquer ($17.00 for 0.50 fl. oz.) is described as a "soft plum with silver glitter." It's a pink-plum with silver glitter--but the way the glitter sits against the pink-plum makes it appear almost like a really pale, silvered lilac. I couldn't think of any good dupes for it, but Nubar Treasure Nail (darker purple) and Milani Hi-Res (holographic, darker) were the closest--I wouldn't say they're close, though.
Continuing with the same hues that have made NARS Nail Polish a coveted favorite, NARS introduces a new technology to its Nail Polish, specifically designed to help improve the formula's flexibility, durability, wear and gloss properties. NARS reintroduces its Nail Polish with a newly developed polymer system that provides extended wear and a tough, durable, chip-resistant finish. The superior longwearing formula also imparts an initial high-gloss luster with prolonged gloss retention, and is also water and detergent resistant with additional UV protection to prevent polish discoloration.
