Reychellle,
[First,.... love your name. So exotic and soft sounding that rolls off the tongue.]
What an intriguing thought. I never once considered the previous owner of my many thrift shop items. I should though. Interesting.
I usually launder a new thrift store purchase (first thing) for sanitary reasons. I don't take time to sniff them for scents or hints of other humans. But I can see where clothes may carry an animating spirit within them; or as you say, what was the previous owner all about.
BTW.... The Thrift Store is your best friend. I find the most amazing, sometimes fashionably old-fashioned, and sometimes unique dresses and outfits there; all for pennies on the dollar. I bought a great Calvin Klein blouse that I know was probably $80 new retail for $7.
I have a dressing day today. I may go to The Veterans Store. Thanks.
