Be not too eager for rich apparel, for humility is incompatible with a love of display. One who is too solicitous about his dress is a slave to the opinions of men, for he certainly would not expend so much labor upon it if he thought he would not be observed. Beware, however, of going to the other extreme and dressing in a manner unsuited to your position. While claiming to despise the approbation or notice of the world, many secretly strive for it by their singularity and exaggerated simplicity.
