I have a friend who made it in a clothing discount store of a certain brand. As for the goods inside, it can't be said to be true or false, but my friends often collect the stocks of other brands and then change them into trademarks and tags.

So if you want to buy it, you must see if the trademark (usually at the neckline) has been removed, and then see if the logo embroidered on the chest (many brands embroider the logo on the chest) is consistent with the trademark on the tag.

Of course, going to the brand clothing discount store is mainly for the price. Don't care too much about the brand if the price is ok.
