I agree with Cruella. Also, make sure if you like the texture since it's matte, as you probaby know.
I normally wear pale lipsticks like you do, but sometimes I try intense colors such as Tassle and Rockocco. I love them, but I didn't like some darker colors on me like Lovemate and I don't swap any cosmetics especially if they're used, so I just gave it to my mother. And it's needless to say that if you ever get the chance to go to a MAC store or counter, try it on yourself before you decide to buy it. I've bought some lip products just because I liked how they looked on people's lips in *pictures*...and I didn't like them on me or didn't like how they looked in person. So it's always best if you can get to see the actual color.
