Women must not wear men's clothing

This mitzvah forbids women from dressing in men’s clothing or adopting styles and ornaments specifically associated with men. The Torah views this as an abomination, since cross-dressing blurs divinely established distinctions between the sexes and can lead to immorality or participation in idolatrous customs. The mitzvah safeguards modesty, holiness, and the integrity of Jewish identity.

Commentary & Classical Explanation:

• Rambam (Hilchot Avodat Kochavim 12:10): Explains that the prohibition applies when cross-dressing is for immorality, disguise, or participation in idolatrous rituals.
• Sefer HaChinuch (Mitzvah 542): States that the root is to distance Israel from practices that blur boundaries and lead to sin.
• Talmud (Nazir 59a): Teaches that this prohibition is tied to avoiding the ways of idolaters, who would dress in opposite-gender clothing during pagan ceremonies.
