In my yeshiva they have a copy of rabbi falks sefer lying around. I read through it and it left me with a very uncomfortable feeling it seemed like the “taliban guide to judiasm”. Still he was rabbi and who am I to argue with halacha so I discussed it with one of my rebeim. he told me that the halachos brought down are the the most machmir of every shita (as opposed with sticking with one shita both for kulos and chumros I guess the reverse of taking every heter you hear of). In addition to the “halacha” he brought down he brought down every extra chumra he could think of as what a frum girl should be doing. Reading the book made me feel depressed and I can imagine how inadequate it makes girls who cant live up to its extreme version of tznius feel. i personally don’t agree with the idea of taking every single case and scenario and writing a 500 page book on it just like I don’t agree with writing a 500 page book on how a yeshiva bachur should act in every single situation. these things are a sensitivity that should taught by personal example and by personally teaching the basic guidelines. with the sensitivity woman will be able to figure out on their own ( whether it is too tight short etc.) without sensitivity you can write all the rules in the world but woman won’t be in the spirit of tznius (even following all the rules) sensitivity must be developed over time and a huge book does nothing but throw people off.
Another thing girls have to be taught is that tznius doesn’t mean make yourself look ugly. I was recently by a shabbos meal where there were about ten seminary girls from very frum seminaries 9don’t worry they were at the other end of a very big table separated by a virtual mechitza) and none of the girls were at all attractive. not because of them but because of the clothes they were wearing. tznius doesn’t mean wear sackcloth. these girls are going into shidduchim soon and I wonder if anyone told these girls that even the most yeshivish bachur is going to have to be attracted to them to marry them. If you dress like you are ashamed of your body it’s going to be difficult for a guy to get attracted to you. also ditch all the black it looks like you are going to a funeral all the time
