Selfridges is most definitely NOT high street! Also it's Marks & Spencer, no 's' on the end. And I wouldn't consider Boots or Mothercare fashion high street shops. Plus there are a lot missing, like Oasis, Warehouse, Wallis, Office etc.
Definitely should be a next. If accessorize is in there then claire's accessorize should be. Wondered if there would be a jane norman+fat face but no, so didn't bother trying self ridges... If Boots is here then Lloyds and superdrug should be too. I wouldn't think BHS is one of the top ones as mostly it has shut down now...
