When I’m looking to splurge on an eyeshadow, yeah. For everyday and for travel I’ll often use an inexpensive (drugstore) trio of neutral shades, but if I want a richer, more textured look or a really special shade for a big night out (try Outremer as a liquid liner), it doesn’t get much better than NARS.
A great shade to try to test out the line for yourself: Ondine, a pinky-brown with a little shimmer that looks great on everyone, and in every season.
