My son is leaving to camp before Tisha b’av. His pants are ripped. Are we allowed to sew this up during the nine days?
It is permitted to fix ripped clothing, however alterations on new clothing is problematic. If you are stuck and your son won’t have what to wear, you can be lenient.
O:CH 551-7, Igros Moshe O:CH 3-79, Shevet Halevi 10-81(5), Halichos Shlomo- 14-16, Kovetz Halachos 13-1. If the child won’t have pants to wear if they don’t get altered beforehand, it would be considered a davar ha’aved and permitted. Poskim
