Hi, can you please post a close-up of the label in the last photo? I can just make out "Toulouse", so it may be French, but nothing else, because the print is partially faded. In a close-up we might be able to read more and that label might have some good clues. I am not a lingerie specialist, so I can't say much about your pretty corset right now, but I'm sure someone who knows more about these will come along.
