The absolute worst people are the ones that go to sample sales or stores and buy shit they have no intention of wearing, but intend to sell on a forum or eBay. Stuff like that should be left for people who will actually wear it and love it. It's even worse for diffusion lines and collaborations, which are actually supposed to make designers more accessible to regular consumers, not the hardcore cult of fans who already love the brand. Don't get sad no one wants to pay triple the price for your H&M x Maison Martin Margiela hangers.
