I love this blush color! The Nars blush in Sin is a cool mauve with fine shimmer that doesn’t end up looking glittery on the skin. The color can build up nicely, and it applies and blends well. It also wears well, and is a good option when you’re looking for a cool-toned blush shade. I find it super flattering on my skin, even though I’m deeper on the skin spectrum and have a warm undertone. NARS is a pricey brand, but it’s worth looking for a deluxe sample or kit (which often is a better deal). Swatch attached.
