Do you like goodwill or prefer local thrift shops?
Goodwill is ok, but their prices have gotten a bit ridiculous lately.  I prefer the local ones though  - more of a treasure hunt
Did the love of vintage clothing come from being in thrift stores or the other way around?
You know, I'm really not sure.  Maybe the nostalgia of days gone by came first as far as fashion goes, but i've always loved the treasure hunt aspect even if I'm not shopping for clothes.
Well considering you enjoy vintage clothing, and the hunt, I'm sure sometimes you can't get the whole outfit but have you checked out ragstock.com they have a huge selection.
I've never heard of that place.  Is it all vintage clothing?
It has both new and vintage clothing. but the difference is it's not "designer vintage" its actually from that era. At the same time you can get a new band shirt at the same place.
I'll have to look into that - some places that sell stuff that really is vintage want a lot of money for it.  I found a pair of old levis, like literal holes and excessive wear, and they wanted $50
That would be the downside of supply and demand.  As the days go by the supply for vintage anything is going down while at the same time there is a revival of all thing older.  You're probably going to do better in a thrift store than an online retailer for price.
I know - I wish I had all those clothes from the 80s/90s now
That's funny because thanks to me never throwing out any clothes i have all of that from when I was a teenage and in my 20's.  Maybe ask friends parents, they maight have done the same as me and never threw it out.
That's a great idea thanks!
Well good luck in the hunt. Hope you find that uber popular black mesh shirt from the early 90's
