Satin Slip is a warm-toned, peach-orange with gold and pink shimmer. It is semi-sheer on lips; it darkens my natural lip color and adds a fair amount of shimmer. I really felt the grit of the sparkle in this particular shade right off the bat, which was unexpected. It wore for three hours. Revlon Sunset Peach is a smidgen darker. MAC Spirits-a-flyin’ doesn’t have pink shimmer.
