Thanks Jonathan & Nicole.
It makes sense if it's 80s Jonathan. The wardrobe I acquired from this one woman stops in the late 80s, but then I was confused with the label - I guess the label in the resource for the 2000s must have started sometime in the 80s.
Nicole the tags and the zipper are in the back, but I can see why you might think that - it's a very daring neck opening.
