MAC Good Form is a slightly warm-toned, medium-dark copper with a pearl finish. It is a permanent lipstick that retails for $19.00 and contains 0.1 oz.
MAC Good Form Lipstick ($18.50 for 0.1 oz.) is a medium-dark, coppery-red with warm undertones and a fine, pearly sheen. It had a "Lustre" finish, which meant it wasn't supposed to be full coverage (like most of the MAC lipstick finishes), though it still had more medium to semi-opaque color payoff in a single layer. The texture was thin, lightly emollient, but it didn't feel clingy and didn't settle into my lip lines. It stayed on well for three and a half hours and was neither drying nor hydrating on me.
