You should not wash any laundry during the nine days;17See note 11. not even a shirt or a garment that you will not wear until after the fast day. It is forbidden even to have it washed by a non-Jewish washerwoman.18If you must leave on a distant journey during the week of Tisha beAv, it is permitted to have the clothes needed for the trip laundered by a non-Jew. (Ibid. 551:39) A Jewish woman is permitted to wash the clothes of a non-Jew; nevertheless, during the week in which Tishah beAv occurs, she should be diligent [not to do this work].19In a situation where there is a question of providing food for her family, this would be permitted. (Ibid. 551:42) During these nine days, it is also forbidden to put on laundered clothing, or to spread linen, even if they were washed before. However in honor of Shabbos, you may put on clean linen garments (undershirts and socks) and spread a fresh tablecloth on the table, and change washcloths and towels, just as you do on other Shabbosos.20The Vilna Gaon permitted the wearing of regular Shabbos clothing on the Shabbos before Tishah beAv. Rav Yaakov Emden permitted wearing Shabbos clothing, even when Tishah beAv occured on Shabbos and was postponed until Sunday. (See Kitzur Shulchan Aruch, paragraph 16) (Ibid. 551:6) But it is forbidden to spread clean sheets. A woman who is required to put on clean white undergarments when she begins to count the seven clean days, is permitted to wash her undergarments, and to put them on. Also diapers, which are dirtied constantly, may be washed.21Other types of infants’ and children’s clothing may also be washed. You should, however, not wash a large amount of clothes at one time. (Ibid. 551:82,83)
