Rabbi Moshe Sternbuch criticized the custom of dressing up in offensive costumes for Purim in a shiur at his yeshiva.
“Those who like to seem like they look like they look like they look like they. ‘Rabb ‘there’ look and ‘there’ look. a ‘there a ‘there’ appearance. They don’t want to be identified as yeshiva bochurim; instead, they appear to be goyim or secular Jews.
“One needs to know that clothes influence a person’s character. Amalek allegedly changed their language to a Canaanite dialect when they came to battle Israel so that Am Yisrael wouldn’t recognize them. Why didn’t they change their attire, the critics ponder?
The Belzer rebbe said they would have become Canaanites if they had changed their clothing because one’s appearance influences their essence.
“So individuals who dress in inexpensive clothes are in tremendous danger, and one must beware of dressed in street-style clothes as they are ugly.
On the other hand, if a yeshiva student behaves and dresses like a Ben Torah on Purim, it is a great Kiddush Hashem, as our sages say, “And you shall love Hashem your G-d-act so that Hashem’s name is revered because of you, see so-and-so how admirable are his actions, happy is the father who taught him Torah, happy is the rabbi who taught him Torah.
Every yeshiva bachur should strive to sanctify Hashem’s name because the rewards are immeasurable, said Rav Sternbuch.
