Deuteronomy 22:5

The woman shall not wear that which pertaineth unto a man, literally, "Not shall be the vessels, the clothes, of a man upon a woman," neither shall a man put on a woman's garment; for all that do so are abomination unto the Lord, thy God. The vessels and clothing referred to include all the special articles of wear and use peculiar to the one or the other sex; for the Lord did not want the children of Israel to ignore the difference of the sexes, as it had been fixed in creation.
