Oh wow, I didn't know there were fakes until reading your post. Well-done, Velony!
I had a quick read of the adverts on iOffer. Some seller was slightly more honest than others because some still insist what they sell is a mix of silk and cashmere or pure cashmere (yeah right!); but some did point out the version they sell is a mix of cotton and linen. According to their pictures, I'm sure what both sides sell are the same fake stuff. I think the texture of the fake one does look quite different from an authentic one; so does the fraying hem.
