Is it Tznius for a woman to daven in a public place (i.e on the street or on the train)? If not, should a woman rather daven after Shkiah than daven in a public area?
The Issur to daven in an outdoor public area applies to both men and woman unless one is traveling (see Alter Rebbe 90:5). However, there is nothing not Tznius about a woman davening where men are present. L’chatchilla one shouldn’t daven Mincha after Shkiah, but one should not protest against those who are lenient. (Seder Hachnosas Shabbos).
