Mirror mirror on the wall, who is the fairest of them all?

I come in different shapes
I come in different sizes
I come in different hues
I come at different prices

I show what I see
however ugly however fair
not what u expect to see
an individual, a group or a pair

Regardless of gender
I am important to all
tall or short
big or small

I am truthful
for i have no one to fear
no matter who, no matter what,
I am always faithful.......
