Brookyln, there are many different halachic opinions on what constitutes dressing tzanua. For example, my Rabbi allows me to wear pants (I need them for work). He also allows slits and shoes/sandals without socks. So I am following my Rabbi, but the OP didnt allow for any of that! She just stated “her list.” I am not saying my list is for everyone, just that her list is not either.
As for her point about women covering all their hair (except possibly for a tefach) – this is a machlokes also! There are opinions that say only a HEAD covering is neccesary, there are those that say not even a tefach can show. That list caters to a specific group of people and is not halacha across the board.
