Vintage- representing the high quality of a past time: vintage cars;vintage movies. old-fashioned.
Here is what I think about this topic, if you buy something at the thrift store it does not mean that it is "vintage" it just means that you bought it at the thrift store. I know someone that bought shoes at the thrift store and keeps telling everyone that they are "vintage" when I was out shopping this weekend I saw the same shoes at a department store. So I guess if you buy it at the thrift store it is automatically "vintage".
Maybe I should start buying everything at the thrift store because that means that all my cloths will be "vintage". ha ha Now if it's from the 1950 then I would consider that item to be vintage because it is actually "vintage".
Sorry about the rant but I just needed to put it out there.
