A completely indifferent attitude toward clothes in women seems to me to be an admission of inferiority, of perverseness, or of alack of realization of her place in the world as a woman. Or--what is even more hopeless and pathetic--it's an admission that she has given up, that she is beaten, and refuses longer to stand up to the world.
