To be honest the reason designer brands like Lanvin and Margiela create abominations instead of re-releasing classics is rooted in the nature of these lux companies. If they created the same shit over and over, it would lose the exclusivity and rarity of designer merchandise. By coming up with new designs (as bad as they are), these companies are constantly ahead of the curve (figuratively speaking) even if they keep coming out with shitty new ideas. Many copycats hop on board for successful old designs, which ruins the exclusivity and rarity set by these high-end brands. Once that happens, there is less incentive for customers to buy from expensive designers like Lanvin. Lanvin has to create designs that are hard to imitate. By using rare and lux materials, as ugly as they may be- are very hard to imitate which set's their brand apart from any other ripoff or midmarket brand. All the rare materials, odd construction techniques, etc that they are doing now are VERY hard to copy and it makes the shoes their own. That being said, they're all ugly as hell and sometimes it pays to capitalize on successful product especially if that's what customers want. That's why Diesel buying margiela was somewhat of a good idea. The house can now re-release classic items (5-zip, lowtop trainers in classic cw's) without suffering the fashion house dilemma to constantly innovate.
