Bustier (Creme Gel Liner) is described as a "deep blackened olive." It's a murky, blackened brown with hints of khaki/green in the base, but it reads fairly black overall. There appear to be very, very fine emerald shimmers in it. The texture was lightly creamy and didn't tug on the lash line. One stroke yielded semi-opaque pigmentation, while two to three layers achieved full opacity. This shade stayed on well for eight and a half hours.

Precision of a liquid with the ease of a gel based formula. Apply with a brush, we like a super fine, firm and synthetic angled brush. Dip tip of the brush, coat both sides – be careful not to pick up too much product! Work quickly, as the formula becomes transfer resistant once it dries. Do NOT leave opened for long periods of time or it will dry out and you will be sad. Be sure to close the lid tightly after each use.
