Clothing during Shloshim

Do not wear newly purchased clothing during the first 30 days of mourning (shloshim).  You may wear new clothing from the end of shiv'a if someone else wears them somewhat before you do. 
Note Restrictions on newly purchased clothing end after:
  • the year of mourning for those mourning for parents, and
  • 30 days for those mourning for other relatives.
