Guerlain Mirage (06) Terracotta Khol ($35.00 for 0.03 oz.) is a loose eyeliner or khol. It’s from this year’s Terracotta Collection. Mirage is a smoldering, smoked out gray-toned brown. It’s a nice, smoky shade, but since it’s not black but brown, it can be worn in the day time without overdoing it.
