So you have no issue with a morah in a denim skirt, t-shirt and snood, so long as she is neat and clean? I don’t want to put words in your mouth but its pretty much the opposite of many things you have said so far, unless I totally missed the boat.
My kids best morahs were the ones in denim and snoods. The morahs who were always prim and proper were to busy worrying about their nails or their clothing than helping my child with the project.
In the business worl, I’ve worked in companies where the dress code for men was a suit and tie (tie worn all day, jacket they “allowed” you to take off) and in a company where the dress code is “as long as its not jeans and a t-shirt”. I didn’t find that the mode of dress set the tone for the office. Those in charge set the tone with their attitude.
Perhaps my attitude towards clothing stems from the fact that I’m not from the “chitzonios is meorer the pnimuis” crowd.
