It was stated that, "Orthodox Judaism has sexual undertones."
Just because Orthodox Jewish girls go running around in these tight skirts above the knees with a slit halfway up to their you know what crack in the back doesn't mean it's the Orthodox Judaism that has the sexual undertones.
Humans, more men than women, are sexually driven and Orthodox Jews twist and bend the rules that are supposed to deal with that into what they want. Unfortunately, wearing a revealing sexy tight skirt is more ok than pants in the Orthodox world.
It is unfortunate that rabbis don't speak out more about this. Seriously, there is so much emphasis on wearing skirts and dresses only for Jewish women that no one speaks out about the kind of skirts that are being sold in stores like Junees and Elzees which are "Jewish" clothing stores and yet these skirts are not proper attire for a good Jewish girl.
