MAC Bad Girl RiRi is a moderately warm-toned, light-medium brown with a matte finish. It is a limited edition lipstick that retails for $21.00 and contains 0.1 oz.
MAC Bad Girl RiRi Lipstick ($16.50 for 0.10 oz.) is described as a "matte taupey nude [with a Matte finish]." It's a medium-dark, rosy brown with warm undertones and a matte finish. It had rich, opaque color coverage, and the consistency was just lightly creamy--enough that it didn't tug or pull at the lips much but still left a matte finish behind. It wore well for five and a half hours and was neither drying nor hydrating. It's nothing like Nude from the fall collection. Bobbi Brown Soft Nude (P, $24.00) is glossier. MAC Spice (LE, $15.00) is not quite as warm-toned and has a sheen but is still very similar. MAC Shanghai Spice (LE, $15.00) is lighter, less matte. MAC Double Shot (P, $15.00) is browner, less matte. MAC Brick-o-la (P, $15.00) is pinker. Guerlain Avarice (P, $49.50) is similar. Burberry Antique Pink (303) (P, $30.00) is lighter just a smidgen. Bobbi Brown Uber Nude (P, $24.00) is browner, less matte. See comparison swatches.
