I’d say late 1960s or 70s. If you Google Malouf lingerie or Malouf perfect negligee there’s a fair amount of other examples available, pretty much all of them claiming to be 1960s or 70s. I found an article about the daughter helping Malouf sort through stuff after the closure of the business in the 1980s and being inspired to start her own business. Hopefully, someone will be along who can zero in on the date better. Love the pink!
I know it’s fabulous. Thanks that’s helpful Found it today in Tetbury in a charity shop Not sure if to sell or float around the house in it
