Kilobear, first of all, I had tried to post an apology to you about my overly harsh language in an earlier thread, but by the time I did, the thread was closed. If by getting upset about ahavas yisroel causes somebody to feel bad then I have defeated my whole purpose.
Second, I personally agree that one should wear socks, and make sure my daughters do. I also do not wear jeans, and feel funny when I see in some shuls the one giving a shiur between mincha and maariv is wearing jeans and a T-shirt. Nevertheless, these people are machshiv Torah and it sends a positive msg when the teens in shul see a “cool guy” who is teaching the words of the Mishna Berurah and expounding on his sevaros. They see that one can be just like them and still be involved in learning. So there are two sides to everything.
But my complaint about the tznius book, is that dignity is a personal matter, and you don’t legislate it or start making up all kinds of rules that have no sources behind them such as how blue or green socks reflect light a certain way. One should not micromanage tznius to the point that it looks like OCD disorder. It should be mentioned that we must dress dignified and befitting, and zehu. Girls aren’t morons who need to be spelled out every single detail. This stifling set of arbitrary rules filling the book many of which have the most tenuous source if at all, will do nothing but turn off people or cause fights by people who think they really are halacha.
Another example of a source is that tight garments are forbidden because of the pasuk in shir hashirim which says chamukei yeraychayech, from which Chazal darshen mah yerech bsayser, af divrei torah bsayser. (And since it doesn’t say mechuseh, the author concludes the form can’t show.) The drasha has nothing to do with tznius of dress. It has to do with keeping sisrei torah secret. (Otherwise it would be a bah lelamed, vnimtzah lamed.) It is saying that the metzius is that the yerech is bsayser, so therefore we must keep divrei torah bsayser. An analogy is dadecha yirvucha bchol es, mah dad zeh kol zman shatinok memashmesh bo motzai taam, af divrei torah kein. It is not a chiyuv on the tinok, it is using a metzius to learn the nimshal.
Lately it is fashionable to use shiur charts on pesach. Now a kzayis is certainly a halacha with many sources written about it. However, I gurantee you that previous generations and even the gedolim of those times did not use them even for this mitzvah d’oraisa. They ate matzah bsimchah but did not get OCD over it. Whatever they ate was good enough. They estimated the size of an olive or beitzah and that was it.
Tznius by definition means being private. To write a whole book on your opinion of how girls should dress in the most excruciating detail seems to be the exact opposite of tznius.
