According to the religious Zionist weekly Matzav Haruach, the following sign appeared in a playground in the haredi neighborhood of Neve Yaakov in Jerusalem:
According to the suggestion of our teacher the great rabbi H. Kanievsky, women are requested as follows, to divide seating in the city according to groups of women. Women dressed appropriately (wide clothes, a properly covered neck, a modest scarf [MiI: to cover hair]) will sit on separate benches. Women dressed immodestly [bepritzut] Heaven forbid, (tight clothes/open collar/bandana) will sit by themselves. And in this merit the women [MiI: there’s no question as to which women, even though the wording is vague] will merit viable offspring, a comfortable living, and true comfort [nachat] from their children.
Notice that the suggestion is not directed at women who wear pants, show cleavage, or (married women) who leave their hair uncovered. The target appears to be women who more or less follow the rules, but fall from the community standard or the standard of whoever wrote the sign. There is even a subtle dig at wigs, as they are not mentioned in the description of modest clothing. Wigs are verboten in more modest circles.
Somehow I don’t think ostracizing women in the park is going to make anyone start dressing more modestly. And the implication of this sign—that a woman who wears a bandanna is contaminating someone who wears a modest scarf—is scary. We should be glad that children of prutzot are still allowed to play in the park with the children of righteous women.
