mdd: I also gave her some definite answers, didn’t I?
Yes, one small very obvious point. Something that by the age of 12 a frum girl can ascertain themselves. I highly doubt she and her female family members didn’t already know that.

Growing up in a ffb home, a woman develops a very good understanding of what is acceptable for tznius and how things look in the eyes of others. I have not seen anywhere in the cr that the men posting here know the halochic gedorim better in regard to tznius. Most just give their own opinions here anyway.
Wny not ask a Rov? Some are embarrassed to do it.
Why not apply this to your next question?
