Here's an impressive striped top by Nina Boutique. The reason I'm impressed is that it's so carefully cut; one could call it sculptural. I've tried to bring that out in the last three photos.
I'm told that this top would have been made in the late 70's, perhaps on sale for evening wear from a small boutique in an area such as Chelsea or Kensington . It could have cost around £400, which would have been several weeks' wages.
