From what I've seen this lipstick looks quite similar to MAC's Frost Lipstick in O. Not exact, but close enough to mention. It's also similar in shade to MAC's Frost Lipstick in Fetish. It's like a mix of the two.
The colour is a plummy red with brown undertones - also with a hint of shimmer. It's a difficult shade to describe. Sometimes it comes across rather bronze/coppery depending on the light.
For me I think it's a little too mature, and a little too warm. I could probably make it work by dabbing it on and pairing it with a lighter gloss. I can see that it would look good in autumn/winter if dark lipsticks are your thing. It would look great on women with deeper skin tones.
