I think the market is totally over-stretched. Too many shops and too many of particular shops. Greedy corporate owners. Lots of stuff in clothing shops is just cheap 'pile it high' tat that will end up as landfill within months. The mid-range is often over-priced and rarely has much quality to it. The top end is silly money and Kings New Clothes.
We have built hideous blot on the landscape out of town shopping parks and killed our high streets with that and online shopping.
Within a 10 miles radius of our house there are 12 Next stores, 10 Marks and Spencer, 26 Sainburys, 8 H&M, 5 Sports Direct, 4 White Stuff, 5 Fat Face, 9 Argos. Almost all are big out of town stores and take business from the high street and sell 'pile em high' tat- often presented as not that.
