A blue garment, unless it be of silk or wool, is improper for any caste except a ´Súdra, but a Bráhman's wife at night, and a Kshatriya woman as a bride or at a feast, may wear it, and a Vaiśya woman must avoid it when performing the ´Sráddha or funeral rites. The women of all three castes may not wear it when cooking or eating.
