Giorgio Armani #604 Plum Gloss d’Armani ($28.00 for 0.22 fl. oz.) is described as “bold amethyst.” It’s a sheer grape purple, and when applied to lips, it looks like a cool-toned plum-purple. It reminded me of Illamasqua Fierce when it swatched, but they’re nothing alike on the lips. I couldn’t think of any other potential gloss dupes.
