“I thought erva was a halachic status, not necessarily a visual thing. You can’t see “erva” itself, you see body parts or hair that IS erva.”
but whats the reason for the Halacha? so that a man should be able to tell the difference between a girl and a woman. if we wear shaitels that look like our hair we are defeating the purpose.
about daughters of dignity it is written by someone friedman. but the names of the gedolim who she quoted i’ll post bl”n some other time. i do rememeber though, they were chassidish and litvish gedolim.
