I will show the difference between a fake abercrombie jeans and a real one.

First on the label the fake one has an error on it. It is written "estaslished" instead of "established" and the label is not the same size and color.

On the other label, on the fake jeans, after a wash the words are erased and on the real one the words are still there.

On the pocket inside the fake jeans, the words are blur with a lot of white ink. On the real jeans the words are not blur and have an used, vintage style.

On the button fly inside the jeans, on the fake jeans it is written "lo wrise" and you see 1892 on the back of the buttons. On the real jeans, it is written "lowrise" and there are no 1892 on the back of the buttons.

The paints spots on the fake jeans are like that. It is an ocean wash.

On the real one there are like that

hope it helps
