just a heads up for anyone who doesn't know yet but these things do exist. just a warning for those who buy basics off grailed or ebay.
honestly you can take a random black thrifted jacket that looks somewhat in the style of undercover, throw the tag on it and sell it without people knowing.
same with acne, same with stone island.
you can easily tell fakes though. The tags are usually the easiest thing to counterfeit on any label, no matter how lux, there are always ways to reproduce the look if not the manufacturing process.
Anyways your garments are harder to fake considering fabrics and stitching will never be identical.
