Clothing & Sensitivity

(Illustration by Yechiel Offner)

It is customary to say to a person who puts on a new garment, "May you wear it out and acquire a new one." But to someone who puts on new shoes or a new garment made out of fur or leather, even if the fur or leather is from an unclean animal and even if the fur or the leather are only used as lining, do not say, "May you wear it out and acquire a new one," because a new garment like this one requires killing of a living creature, and it is written, "And His mercies are on all His works."

(Kitzur Shulchan Aruch 59:13)
