NARS Giza is a slightly warm-toned, dark peach with a cream finish. It is a permanent lipgloss that retails for $26.00 and contains 0.18 oz.
Giza is described as a "sheer nectar." It's a medium, slightly muted, peachy-orange with a creamy, glossy finish. It had semi-sheer color payoff, which meant that the natural lip color influenced the outcome of the gloss--on me, that meant that some of the orange was lost and the gloss looked more like a pinky-peach. It wore well for four hours. MAC Ray of Sunshine (P, $22.00) is darker, warmer. MAC Lovingly Yours (P, $22.00) is lighter, pinker. MAC Cheerful (P, $22.00) is darker, warmer. MAC Be Nice (P, $22.00) is pinker, less warm-toned. Bobbi Brown Nectar (LE, $24.00) is much lighter, cooler-toned. Urban Decay Rule34 (P, $20.00) is sheerer. MAC Persistent Peach (P, $19.50) is lighter, more opaque. MAC Everlasting Nude (LE, $19.50) is darker. See comparison swatches / view dupes.
