Knock Twice Hold the Line Eyeliner ($17.00 for 0.04 oz.) is described as a “metallic deep champagne.” It’s a soft, muted bronze with a champagne shimmer-sheen finish. It’s darker than champagne, but it’s not too dark–this shade gets completely lost against my skin tone, as a reference, and I would not recommend for anyone who has a similar skin tone (it just feels like it never shows up to the party) but it may work well on fairer and deeper complexions where there would be more contrast. I wish it was a champagne, though, as it would work well for brightening in particular! This shade was also sheer when applied in one layer, and it was buildable in three to four layers to about 80% opacity. The consistency was very creamy, though, even if pigment was difficult to get out of it! Knock Twice seemed to wear well for ten hours on me–I used a magnifying mirror and was able to at least see the shimmer and a slight darkening, but it wasn’t quite as easy to measure the wear compared to the other shades (on me). MAC Deliciously Rich is a gel eyeliner, and the color is darker and has more sparkle. Urban Decay Hustle is darker and warmer. See comparison swatches.
