Good morning/afternoon/night, How was Christmas, everyone? Hope it went well for all. I bought this lashing blouse (if that's what it's called; correct me if I'm wrong) in a local charity. It has this very aged tag with the designer’s name and the name of my city. I couldn't get any info on her searching the web, but my hunch is that this piece dates back to the 70s. Am I correct? Thanks for any help. - J.P.
