Just making a point: Every time there is a shiur on Tznius, many people think “uuggghhhh another speech” but when its up for discussion in the coffee room, its one of the most commented-on threads!
The reason for this is because everyone knows deep down what the Halachos are, but your just trying to find loopholes. Well guess what? I’ve got news for you: THERE ARE NONE!
So throw away your short skirts and tight shirts and learn the Halachos!
