1. Look at the double sutures. Genuine Levi's jeans are made with fine workmanship. The trouser legs are sewn in double layers. The two double stitches on the inner thighs are two different colors, while the fakes are basically single-layer stitches. Although the genuine ones also have single-layer stitches. But there are very few, and many of the double stitches on the fakes are white, while the authentic ones are sewn with thick gold threads.

2. Look at the logo. Genuine Levi's jeans should have two Levi's logos on the back pocket, one front and one reverse. The letter e is a lowercase letter, and some early authentic products have a capital e. Moreover, genuine products have the LS&CO logo on the copper nails in pockets and other places, and the word Levis on the zippers and buttons, while fakes generally do not.

3. Look at the main buckle at the waist. The big button on the authentic Levi's jeans is made of brass. It has been worn for a long time and there are very few scratches. The fakes are usually just similar in shape, and the color and material can be seen at a glance. .

4. Look at the rivets. The rivets on authentic Levi's jeans are standard brass material, darker in color, and very thick, while the rivets on fakes are thin, some have threaded textures, and look shiny. The rivet part on the reverse side of the genuine trousers button has the same number as the wash mark, but the fake ones do not.

5. Look at the red label. The red label is one of the most prominent parts of Levi's jeans. "LEVI'S" and "R" (registration symbol) are perfectly printed on the red label to indicate authenticity. The red tags on authentic Levi's jeans will be perfectly cut and sewn onto the pockets of the jeans, while fakes will have messy cuts, misaligned or unevenly sewn onto the pockets.
