I only speak for myself, and don't have that particular suit, but I actually like the democratization of fashion. I just got another pair of Margiela GATs, and I probably wouldn't get knockoffs, for any number of reasons, (I actually like them more than the Dior version, tbh), but am not at al bothered by their existence either. If someone wants the look, but can't or won't pay a few hundred, that is fine with me.
What I do object to is the watering down of designs into a timid, toothless, version.
Doesn't the complete democratization of fashion make it harder for new fashion designers to succeed?
I've also noticed that a lot of people wearing knockoffs don't even know they're knockoffs. They literally have no idea of who made the design, nor do they give a shit. They're just happy they have something that looks like what their friends think is cool. The (total) democratization of fashion leads to the depreciation of fashion as art.
