Thank you so much for taking the time to answer questions. I am learning so much.
My question is with respect to wearing pre-owned clothing from non-family members (i.e. buying second hand items at thrift stores, etc. where we do not know who the previous owner was). Is there any halacha that would discourage this if the clothing is in good condition and is appropriate for the persons budget? Does it bring up any kabbalistic implications in terms of the items being worn before?
It is permitted to buy second hand clothing from a thrift shop, and I am not aware of any halachic or kabbalistic restrictions on this. If you are uncomfortable that is a matter of personal preference. You do however have to be careful that the clothing that you buy is free of shatnez, similar to buying new clothing in a first hand store.
