Explain me this, Snow White

Looking Glass, Looking Glass, on the wall,

Who in this land is the fairest of all?

Why is it that Snow White was marveled upon and the dubbed fairest of them all when her skin is ashen, white as snow? Why is it that her mother longed for "...a child as white as snow, as red as blood, and as black as the wood of the window frame."? Does not black hair make white skin pale? Why was pale white skin desired before this time when now all skin is bronzed? Women refused direct sunlight; They never went out of doors without a sun bonnet or parosell and tanned skin was...ugly. This day in age is quite the opposite, which is a shame. Women, and even men, will buy product after product and expose themselves to the dangers of the sun, all for the sake of a tan-for the sake of temporary and harmful beauty... Perhaps I see it as an issue plainly because I myself am white as snow, and sometimes long for that tanned bronze, but my skin is impossible to color. I am still troubled as to how much the idea of Beauty has changed...So, explain me this, Snow White, for I'm dying to know...
