MAC Plum Bright is a very cool-toned, dark plum with a luminous finish. It is a limited edition lipstick that retails for $19.00 and contains 0.1 oz.
Plum Bright is a reddish plum-purple with semi-opaque color coverage and a glossy shine. The information I have lists it as a satin, but it feels like a lustre or glaze (and looks like it, too). It has a lot of slip and less color payoff than a satin and lacks the overall creamy texture. My tube is a sample and doesn't have final labeling, so I can't confirm either way. MAC Bust Out is lighter and purpler. It's less red compared to Thierry Mugler Dream and MAC Riveting Rose.
