Hmmm...the D'Trick bag has fakes, too, but most of them look so ugly that they are very obviously fake. They look very cheap (that's the first detail), and the holes that are punched into the leather are croaked and uneven (and many of the tiny holes found on the original are missing). The fakes also look unusually flattened (squished from the front), and the pearls are usually all the same size (they go from small to large to small again on the real ones, usually).
And the inside of fake D'Trick bags ALWAYS give them away, because they look extraordinarily fake.
The D'Trick and Hardcore Dior lines (the one with the silk jersey and rhinestone clasp) are the easiest to tell if they are fake.
