Some say you can't combine red and pink together, and I thought: Rules are made to be broken.
And where does that lead us?
I painted the lips in a bright pink (Medium Pencils from Illamasqua shade: Strumpet) and then added a red lipstick (Lipstick Pout from Make Up Store) and smudged the lips together.
And voila! The nicest pink I've seen in a long time!
