There is vintage, and there is Not Vintage Yet. For that, there is Poshmark:
Ever wish you had a style-mate and could shop her closet? Now you can. Poshmark connects you to people whose style you adore, allowing you to shop their closets, anytime you’d like.
Have items in your closet that you love, but just don’t wear anymore? List it for sale on Poshmark in less than 60 seconds. Sell what you have in your closet so you can shop for what you really love today.
Generating a sale listing on Poshmark using their iPhone app — Android is coming — automagically updates your social-media connections, which is how I heard about this in the first place: Rebecca Black is unloading some of her stuff, including this unworn Zara blazer. If you click on “Zara,” everything Zara comes up.
The only downside, I suppose, is that you have to divulge your size. Still, this has the potential to be, um, farking awesome.
