" D&G clothing even contains extra labels with holograms for that purpose"
They're not the only ones. I bought a replica sports shirt; it had 5 separate bits of card with plastic label tags and two of those had holograms.
Unfortunately, I know that the shirt is still a fake; not because of the hologram, (which is actually genuine), but because of the way that it has been stitched together.
The material all comes from the genuine factory where the product is made, as do the labels. But they smuggle all the bits out, then assemble them at home, before selling online at a discounted price. It's actually known about, but the authorities in the country of origin don't give a rats arse; and the licencing authority have no jurisdiction. All they do is warn people.
