A Toe-hold on Propriety

How has society evolved so that it’s taboo to expose breasts, two of the most beautiful things God gave us, but acceptable for any garden-variety tree sloth to go barefoot?   I know someone who grows her toe nails extra long to make her feet look thinner.  Another has a penchant for slides yet the backs of her cankles resemble packed gravel.  And why don’t they arrest women with bunions who insist on flip flops? And the guys? Why is it unseemly if a man enjoys a beer in a public park but okay for him to parade around in Tevas?
