I saw one of the lovely MAC ladies wear this combo of lipstick and lip liner and just had to have them... Its Blankety Amplified Creme Lipstick & Staunchly Stylish Pro Longwear Lip Pencil.
These are the sorts of colours that I would never pick out myself and definitely wouldn't put together... but they work!
The Pro Longwear lip pencil is really smooth, so glides on easily. The make-up artist in MAC told me to colour my whole lip in with it so it holds the lipstick on and so you don't get that dreadful dark lip liner effect from the 80's! Then add the creme lipstick on top, all over, and dab it at the edges to blend. It creates a very unusual taupe/ pink/ beige/ plum colour!
