What does make up mean to you?

Today I had a discussion with my work colleagues about make up and one colleague in particular was against women wearing make up, so it go me thinking - what does make up mean to me?  Personally, I do not wear make up in order to cover up what is beneath, I use it to enhance what nature gave me.  I believe that the confidence that make up can give a woman can only be a good thing and if make up and products give a woman confidence then who is anyone to pass judgement?  Make up to me is a representation of my mood and can completely transform my look depending on my mood that day.  


So fellow bloggers, what I really want to ask is - what does make up mean to you?
