MAC Young Attitude Retro Matte Liquid Lipcolour ($21.00 for 0.17 fl. oz.) is a deep, bluish teal with cool undertones and a mostly matte finish. The formula was thin and a little watery, so the color did not apply as evenly as a lot of the shades from the range have. It had a tendency to appear a little streaky with some areas appearing darker than others. It had semi-opaque coverage, and a second layer would be doable without causing texture/wear issues later on. This shade lasted for seven hours but faded more noticeably from the center of the mouth, while the formula was drying. It did leave a bluish stain behind.
