MAC Shy Girl is a moderately warm-toned, medium-dark peach with a pearl finish. It is a permanent lipstick that retails for $20.00 and contains 0.1 oz.
MAC Shy Girl Lipstick ($17.00 for 0.10 oz.) is a soft, light-medium peach with fine gold and pink pearl. It had semi-opaque pigmentation, which applied fairly evenly across the lips but the more emollient quality of the texture made it prone to sinking into lip lines. The shinier finish helped mask that when viewed at a normal distance, so it was still easily worn on its own but a lip primer or lip liner might help improve the overall finish. The color wore well for four hours and was very lightly hydrating to me. This shade is part of the permanent range.
