29 But let your apparel be plain, not for adornment, but for necessary covering: not to minister to your vanity, but to keep you warm in winter, and to hide the unseemliness of the body: lest under pretence of hiding the unseemliness, thou fall into another kind of unseemliness by your extravagant dress.
Of the Resurrection.
