Because you never know who wore it last:

I want to know where this fascination with vintage clothes shopping originated…
I mean, why do so many people think it is so totally rad to be dressed head to toe in another person’s rags?
I can see how sometimes it would be cool. If you scower the streets of Paris and find a vintage Chanel scarf or some other truly one-of-a-kind trophy piece, let’s say.
But seriously people, what are the chances of you finding a piece that genuine in the Value Village in Niagara Falls?
I’ve tried to hop on to that hipster wagon and catch the vintage shopping buzz. I wanted to see just what was so special about purchasing your entire wardrobe from Value Village. But the moment I walked in I wanted to run screaming into the nearest Holt Renfrew.
However, I decided to give it another chance.
I cruised the aisles one-by-one. I saw old plaid shirts, used bathrobes, a couple wedding dresses. I wanted to gasp at the sight of used socks but the mothball scent was overwhelming me and I started to feel faint.
I did, however, make off with a pair of suspenders. I didn’t want the whole trip to be a bust and I thought they were pretty goofy. Still, I failed to see what all the fuss was about.
I kept imagining the clothes were taken off some old lady corpse and purchasing it would mean I would be forever haunted by ghosts of styles past.
Moral of the blog folks: stick with vintage parisian shops, ditch the sad north american non-equivalents.

maybe the distinction that needs to be made is between thrift shop/charity shop clothing and vintage clothing.
the difference is like junk and antiques. An antique has some value and is special either because who its made by or because its attractive or has historic value. Junk is just junk…
Same with thrift/charity shops…lots of junk. Vintage = antiques of fashion world.
There be good vintage places in London
p.s is that amy winehouse?
