Deuteronomy 22:5

Not wear. This probably refers to the heathen custom — quite common in some lands today — of a simulated change of sex for immoral purposes, men wearing women’s clothes, aping their manners, and offering their bodies for immoral purposes. The word here translated “that which pertaineth” is used of many articles other than clothing, such as “jewels” (Genesis 24:53), “weapons” (Genesis 27:3), “stuff” (Genesis 31:37), “armour” (1 Samuel 14:1, 6), “bag” (1 Samuel 17:40), “furniture” (Nahum 2:9). God made man male and female, and the distinction thus ordained is to be honored and obeyed. The desire to minimize this distinction grows from low ideals and contributes to immorality.
