I've had this lipstick in my MAC collection too long to admit, it is the one that falls to the bottom of the pile and is forgotten about all the time. The lipstick in question is "Plink," a lustre finish which is by no means my favourite finish from MAC, but I feel like this is a good go to, everyday shade for summer. It is a warm baby pink/ peach with shimmers running through it which leaves a lovely glossy looking finish, *a plus* it really helps make your lips look bigger (which I definitely need).
I find the lustre formulation really comfortable to wear and easy to just throw on when you're in a hurry, admittedly with it being a lustre it does mean that it doesn't last as long as other lipsticks, but that's just the way it is with lighter formulations. I find this suits me when I'm at my palest or bronzed up with the help of fake tan, so hopefully an option for a range of different skin tones. Why more people don't rave about Plink I don't know, I know I won't be forgetting about it again! One to have a peak at if you are after a subtle pink everyday shade!
Have you got any MAC lipsticks that you think are underrated?
