I was wondering whether it’s halachically okay for me to dress up as a boy for purim. I wouldn’t wear pants since I’d be a chassidish boy and wear a bekishe. Obviously I’m not using the CR to poskin; I’m just curious about different sources and opinions.
From shulchanaruchharav Web site of HaRav Yaakov Goldstein shlita:
It is accustomed on Purim to allow males to wear the clothing of females and vice versa. This is not forbidden due to the cross-dressing prohibition as the intent is for mere joy [as opposed to promiscuity]. [Rama] [However many Poskim challenge this custom and thus practically one is not to do so.]
