1,256. Sewing the Torn Garment

195:6 For other deceased relatives, if the mourner changed his garment during the week of shiva, he need not tear the new one. For a parent, however, if the mourner changed his clothes on a weekday during shiva, he must tear them. In honor of Shabbos, he should change his clothes and not wear a torn garment. If the mourner doesn't have other garments to change into, he should move the tear to his back. When we say he should change his clothes for Shabbos, we mean into other weekday clothes. Wearing Shabbos clothes during shiva is prohibited, as we will see in 211:10.

195:7 According to the letter of the law, for all other relatives, one is permitted to mend his torn garment with uneven stitches after shiva and to have it sewn properly after shloshim (the 30-day mourning period). For a parent, one may sew with uneven stitches after shloshim but he may never mend it properly. It is not even permitted to cut around the place of the tear and to sew on a patch. However, it is customary not even to sew irregularly even clothes torn for other relatives during the shloshim; even pinning it up is prohibited.

A woman, even for a parent, may irregularly sew the garment right away because of modesty. If one sold a garment that is prohibited to be mended, the buyer is also not permitted to sew them. Therefore, the seller must inform the buyer. It is prohibited to sell such a garment to a non-Jew.
