Giorgio Armani No. 18 Fluid Sheer ($62.00 for 1.0 fl. oz.) is a rich, medium-dark coppery red with lighter gold sparkle. It had sheer coverage, which gives the skin a tint of color and a dewy sheen. A little went a long way, so you can achieve a stronger tint if desired. The sparkle in this shade made it harder to blend over foundation, as it seemed prone to disturbing anything underneath it, but it worked without issue on bare skin. I noticed a few bits of sparkle migrated over night as well, which isn't a problem I've had with other shades in the range. The color itself wore for nine hours.
