The infamous FW17
Most oftenly faked.
60-90% (or even more than 90% with purple/red) on the market are fakes.
Many flaws include sewing technique, none of them has perfect grain (but it may seem different in different lighting so that’s not the best way if you don’t have experience).
Another thing is washtags – there are no perfect ones, they usually miss the font, symbols or the sewing.
Supreme quality control was horrible and so we’ve witnessed not-grey hoodies with 90/10% tags, magenta with wide stitched washtags and so on.
The best way to LC is for now combination of grain – should be diamond stitched, clean, with seam thru the letters, box logo font – not too thick, no touching letters, clear shape, and washtags – with the real font along with the symbols and proportions.
