NARS Lost Coast Eyeshadow Duo ($34.00 for 0.14 oz.) is a new, limited edition duo for summer. It's an interesting mix of shades, but they do work together. One of my favorite aspects to trying out a NARS duo is seeing how the two work together, because you can discover combinations you never thought about before. I was less enamored with this duo as I was Tropical Princess, as the texture was more powdery in both shades here. The left side wasn't as powdery as the right side, and the left side still applied more smoothly, evenly, and had better color payoff than the right side. I found the right side to be powdery, a little chalky, and a shade that really needs a base underneath to help it hold. The left side lasted for almost eight hours, while the right side was noticeably faded after six hours.
