Famous quotes containing the words face and/or gear:
“We see God face to face every hour, and know the savor of Nature.”
—Ralph Waldo Emerson (1803–1882)
“For women ... bras, panties, bathing suits, and other stereotypical gear are visual reminders of a commercial, idealized feminine image that our real and diverse female bodies can’t possibly fit. Without these visual references, each individual woman’s body demands to be accepted on its own terms. We stop being comparatives. We begin to be unique.”
—Gloria Steinem (b. 1934)
