If you believe the stuff you buy in retail store has not been worn, then you are sadly mistaken. At least at a thrift shop, you know it has been previously owned (but not necessarily worn), at the retail shops people return clothes they bought, and worn, but can’t wash (because they can’t take the tags off to return), then the stores just put it back on the rack.
ick. You wear someone else’ funk.
I have always shopped at thrift stores, garage sales, 2nd hand store all my life, at first because we had to, then because I want to. I haven’t liked the fashion at retail stores for the past ? 30 years. Do designers hate women?
Once I got a pair of black leather boots (never worn) at goodwill for $2.50. I wore them every single day (even to bed some nigts) for 6 years straight.
Call me a creature of habit.
