This is Rimmel I ♥ Lasting Finish in Black Cherry. The name is perfect: it's a lovely dark reddy-purple. I've shied away from very dark colours before because they can look cheap and trashy. Not that that's always a bad thing: I spent much of my teenage years trying to look cheap and trashy. But I'm too old for chipped black nailpolish now, I think. Very dark colours really need to be worn carefully to look elegant.
It isn't quite as nice to apply as the other Rimmel polishes I've tried; I don't know if that's because of the dark colour or the fact that it's Rimmel's cheapest line, but the polish is very thick and you need to wait a long time between coats to make sure it doesn't go gooey. Still, I wore this colour twice in a row, which I almost never do.
Note: this was taken in the late afternoon on a winter's day in June. I guess sometimes living in Perth isn't all bad.
