MAC Femme Fatale is a very warm-toned, medium brown with a pearl finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Femme Fatale is described as a "golden brown [with a Satin finish]." It's a medium-dark, warm brown with a soft, gold micro-shimmer and yellow undertones. It had good pigmentation, and the texture was soft, blendable, and only a tiny bit powdery. It stayed well on my lids for seven and a half hours before fading. Sisley Paris Toffee (7) (P, $47.00) is darker. Wet 'n' Wild Naked Truth #5 (P, $2.29) is darker, less yellow-toned. Makeup Geek Brown Sugar (P, $5.99) is darker, more red-toned. theBalm C4 (LE, $16.00) is very similar. CoverGirl Melted Caramel (330) (P, $4.99) is less warm-toned, more shimmery. MAC Glimpse of Flesh (LE, $15.00) is lighter. MAC Exposed (LE, $15.00) is a touch darker, slightly redder. See comparison swatches / view dupes.
