I really don't get why people would pay £200 for a pair of designer jeans when no-one knows they're designer; they look like any old pair of jeans. Waste of money in my opinion. I rarely buy clothes but when I do, I try to find the cheapest stuff.
I choose reasonably priced brands. From the name alone, its reasonable (I know that I get what I want as to what I pay.) For expensive brands it's like buying their popular name+quality (I'm not fan of signature brand and I don't care about the names as long as I know the product is of good quality). For cheap faked brands, its like buying for one or few time use only (disposable with no guaranteed quality and I'm not into that.)
