MAC Pisces Persuasion Superslick Eyeliner ($20.50 for 0.06 fl. oz.) is described as a “shimmery white [with a Frost finish].” It’s a milky white with neutral to slightly cool undertones and a white shimmer. This one was a little more translucent; it applied evenly but the milky white wasn’t fully opaque in one go. I think this might be better layered over something else. I couldn’t think of a dupe for this; I only could think of two eyeliners that were white but both were totally matte.
