A fair bit of the clothing that I bought new and still own, would now be considered "vintage".
The oldest piece of clothing I still have is old enough to vote, and in a year or so will be old enough to drink.
Technically speaking I don't use it anymore; because my wife has expropriated it from me, calling it the most comfortable thing she's ever worn.
Then there's all the old band and pop culture logo t-shirts I own, that if I were pale and skinny with scrubby facial hair would be considered "ironically hip"...
...but as I'm pale, fat, and neatly groomed (well... if I've remembered to shave this morning); I'm just getting old and never throw shit out.
