"No, we're not talking about the fraud of misrepresenting lingerie or other garments or using their logos and labels; but we're talking about cheaper versions of designer pieces.
...Fashion has had knock-offs since it began. And let's be honest; there really are few design innovations in fashion because the human form hasn't really changed. True innovations in textiles and structure are patented and protected. But the look and details can't be protected, not even the red soles of women's shoes. And, overall, they shouldn't be. For, like recipes, you can't protect something nearly anyone can come up with. Or can become inspired by, such as vintage looks. (Heaven knows how much of this "inspired by the past" has played a part in fashion design history.)
Don't mistake this for downplaying the significance of designers or their work. But there are realities to be faced. And that includes, as Coral aka Treacle noted, options for garments and undergarments, including less expensive pieces and a wider spectrum of sizes and fit. Fashion as an industry survives by meeting the needs of all, not a (somewhat literal) slim few."
I'm all about intellectual property rights, acknowledging and respecting one's work; but when it comes to the topic of "fashion knock-offs," I can't help but feel as if designers are judging consumers rather than appraising their own strategies
