MAC Say It Isn't So Dazzleshadow ($21.00 for 0.03 oz.) is described as a "dark grey with pink sparkles." It's a muted, medium-dark gray with silver and pink sparkle over a metallic finish. It was very sparkly, so applied dry, it was less pigmented and more prone to fall out during wear and creased within six hours. Applied damp, it was easier to work with, as it adhered better and lasted a little longer (seven hours) with fall out but not as much as dry application. It wore for ten hours over a glitter adhesive with minimal fall out. Kat Von D Piaf (LE, ) is less shimmery. MAC Tundra (LE, ) is less shimmery. L'Oreal Liquid Diamond (P, $7.99) is less shimmery, lighter. bareMinerals Gunmetal (P, $18.00) is less shimmery. MAC Bao Bao's Jewels #5 (LE, ) is less shimmery, darker. Sleek MakeUP Acid #11 (P, $9.99) is less shimmery. NARS Jardin Perdu (Left) (LE, $24.00) is less shimmery. See comparison swatches / compare dupes side-by-side.
