Guerlain Air Kiss (304) KissKiss Lipstick ($37.00 for 0.12 oz.) is a softened, medium-dark plum with subtle warm undertones and pink and gold shimmer. It had mostly opaque color coverage that felt and looked lightweight and had a glossy shine. I can feel the shimmer slightly when I apply the lipstick, but the color goes on evenly and smoothly. I don’t notice the shimmer in it once on until after three hours of wear. It lasts for four hours on me when I tested it. Estee Lauder Decadent (150) (P, $30.00) is darker, less shimmery. Tom Ford Beauty Bittersweet (03) (LE, $49.00) is slightly warmer. Bobbi Brown Plum Shimmer (3) (P, $25.00) is similar. Chanel Scenario (P, $34.00) is warmer. MAC One of a Kind (LE, $16.00) is sheerer. Giorgio Armani #526 (P, $32.00) is pinker, lighter. See comparison swatches / view dupes.
