Something that’s been around for a while, but no longer holds any real value anymore is often deemed “old” and tossed to the side. Then of course, there are items that actually improve with age, which are given the more distinguished moniker vintage.

In the world of fashion, vintage is (ironically) quite “de rigueur” these days—particularly when it comes to shirts. But not all shirts age equally. Just because a T-shirt has been around for a while, that doesn’t mean it’s actually cool.

So, how do you discern which vintage shirts are still relevant and which are destined to be dust rags? Luckily, we’ve done the heavy lifting for you and narrowed it down to a list of seven different types of vintage shirts that never go out of style—which is being hosted by our friends over on eBay. So before you go dropping 100 bones for that “vintage” California Raisins tee, maybe give it a look.
