Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After eating, you should not go out to the street without having washed your mouth, hands and feet. You should not go out in the evening or with your hair loose, nor should you go out unless you are properly decorated with ornaments. You should not leave the house unless you are very grave and are sufficiently covered.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Kasyapa Muni advised his wife not to go out onto the street unless she was well decorated and well dressed. He did not encourage the miniskirts that have now become fashionable. In Oriental civilization, when a woman goes out onto the street, she must be fully covered so that no man will recognize who she is. All these methods are to be accepted for purification. If one takes to Krsna consciousness, one is fully purified, and thus one remains always transcendental to the contamination of the material world.
