FTB.. yeah.. I heard that the Dior Waxed jeans the wax does start to peel and 'freying' I guess is the right word to use... and... after much wear.. the crotch area might start to tear. MIGHT... not happen to all the jeans...
One solution that was suggested it that if it does start to tear you can start putting patches on it.. so it looks like you have worned for several years... I guess that is what Hedi's inspiration came from which is street wear that is suppose to become old and patched... (I am sure much has been written on this forum about it!)...
One of Hedi's previous assistant has the concept about the cloth that a good pair of jeans should stay with you for the rest of your life. To see you go through your life event. That item becomes intimately attached to you and you alone. I think that concept is still prevalent in a lot of DH collection although not as strong because DH has become more commercial.
Don't you love the irony!
