Israel’s Education Ministry is warning of “panic-inducing costumes” ahead of Purim as the country continues to grapple with the Hamas war that began on October 7. In the shadow of the war and in accordance with the security reality and the characteristics of the current period, care must be taken to avoid dressing up in costumes that may cause fear, panic, or injury to another.
One should wear Shabbat clothing throughout Purim. However there is a custom especially for children to wear masks or costumes. One should ensure that costumes do not contain Shatnez.
Cross-dressing is absolutely forbidden throughout the year. Although the Rema and several other early Achronim rule leniently with regards to Purim, the overwhelming majority forbid it. This prohibition applies to all adults and children who are of the age of Chinuch.
Some people encourage children to shy away from dressing as Haman or other wicked people. [When a Purim play requires a child to act the part of Haman, the Lubavitcher Rebbe indicated that this role be played without considerable enthusiasm.]
