MAC Lipstick in Cyber - £14
This lipstick has been my favourite for some time, especially during the winter months. It's a purple lipstick with brown undertones and gives a slight sheen, but I find it dries my lips out quite a lot (I am a constant victim of chapped lips!) Usually I layer it with a coat of a red lipstick such as MAC's Ruby Woo first and then apply Cyber - it gives a warmer tone and more purple rather than brown.
This is the closest I've got to my perfecting my 90s grunge lip but I'm still open to suggestions - what's your favourite shade of dark lipstick?
