Rav Shmuel Eliyahu, chief rabbi of Tzefas and a son of former Chief Rabbi Rav Mordechai Eliyahu, issued a p’sak two years ago that all men are forbidden to dress as women even on Purim, since the issur of “Lo yiulbash gever simlas isha – Neither shall a man put on a woman’s garment” (Ki Seitzei 22:5) spplies regardless.
In response to a question sent as a text message, Rav Eliyahu noted that some authorities exclude children under the age of 13 from this issur or permit the wearing of one women’s garment, but said that those who follow the ruling strictly will be blessed.
The question and answer was published in the Olam Katan bulletin distributed in Eretz Yisroel.
