MAC Sweet Vapours is a slightly warm-toned, light peach with a frost finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Sweet Vapours is described as a "soft beige with a pink duochrome [with a Pearl Lustre finish]." It's a light-medium, pinky-beige with a cooler pink iridescent sheen paired with gold sparkle. The texture was drier and tended to apply unevenly over the skin, so this one would need a base or primer of some sort to give it a smoother appearance on the skin. It wore well for eight hours.
