I'm sure that you saw the cheap diesel from France on eBay - shioner 801a, Thavar 801c and more.
I bought 2 pairs(shioner 801a 28/32, 29/32), 2 weeks ago from this seller, and he said that is 100% authentic and ....
I got them quickly, and from the first sight I saw the different.
1. The main problem is that the 2 pairs was the same size - 41.5 cm!!!! and as you know, w28/32 need to be 38-39, w29/32 - 39.5-40.5.
2. the label size on the back was in little strange font.
3. the fabric was "cheep" when you touched them, and the jeans don't has any 3d effect.
4. the tags - tag on the back pocket - looks like a copy. the tag with the barcode looks strange, like you can print on the printer machine.
I understand that I need to hear you from the begining and keep away from the french seller (alexkiko) - so I open a case on paypal, returned it and got my money back.
