I know it isn't premium anymore.
But aren't some clothes just mass produced? Like Primark, Walmart clothes? They don't have designers behind them, do they?
I think if it has a well known or prominent designer behind the brand, like Ralph Lauren or Ingo Wiltz, it's definitely designer to me.
I grabbed a black DKNY dress I have, ideal when I travel as it doesn't wrinkle, but it is polyester, it is mass produced in China...
Look, it is not that I am a total snob, I am sitting around with leggings and a Fat Face sweater, a UK brand, not designer, totally high street but also totally comfy....
