I used to love Aubin & Wills, gone about a decade now, I also foresee Jack Wills dissolving if it hasn't already.
I loved Laura Ashley 
I don't know what to think relating to class. Most of the market now seems squarely aimed at the mainstream, or 'economy' group (I can't call this working class as many are very well off). It is class-less, although I do believe the most lucrative customer's are those buying lots, and cheaply. This goes for food, clothes and other lifestyle choices.
What I personally define as traditionally middle class is thin on the ground, from failing radio stations to clothes and TV.
Perhaps 'popular' is the correct term - like watching strictly come whatsit and im a celeb (more intellectual or arty shows are thin on the ground nowadays, as opposed to, say, the 70's to late 90's).
As with similarly popular foods, sports, pursuits etc most of the money is being made here, so brands have no real incentive to cater to a lesser segment of society.
So yes, I suppose the market chose this.
