I had heard rumors of this but apparently this is a real and serious campaign started by women in Crown Heights to entice girls to be “dressed in Tznius attire (i.e. clothing which keep necklines, elbows, knees and feet covered at all times)” for the safety of Israel.
On the one hand, this could be seen as an attempt to have kids show some sort of activism in a situation that makes grownups feel helpless BUT it is again an activism born out on the bodies of girls. I do not see a similar appeal for boys to be dressed in this way.
All this reminds me of the frumkas, the women who wear many layers of clothes, and essentially veil, taking modesty to a whole new level. I have to run but PHEW!
