Reply To: Women wearing tzitzis

5ish unfortunately I don’t know the exact source offhand. All I know is that I learned that certain righteous women (who is course already did all their mitzvos and were eager to do more) discreetly wore Tzitzis underneath their garments. Rashis daughters are one example. Maybe some of the menfolk here have come across this and can give you the exact source.

Again this was not for regular women, it was women of extreme piety.
