It is amazing that people think that. I started shopping at thrift stores in the 1980s. I have a closet full of clothes made by Brooks Brothers, Blass, etc... . As I tell others, people retire and die everyday.
My Dad was a clothes horse. When he died, my Step Mom took to the Salvation Army over 100 dress shirts from Joseph Banks and most were still in the plastic.
Think of thrift shops as hunting, not shopping. You can go into the same store 5 times and not buy a thing. But if the right person retires and donates, you can redo your whole wardrobe for less than $100. I bought my wife a mink stole for $20 and it fits her perfectly.
There are two tricks. 1) Know your manufacturers (quality lasts) and 2) It is not a bargain if you don't wear it (If you pay $10 for the $300 dress and don't wear it, then you wasted $10.).
Mr. b was retiring and didn’t have much in his closet since he had worn uniforms forever. He happened to see an estate sale where the man had died. Mr. b filled up his closet. I think the daughter gave him some of the cloths just happy someone could wear them.
