So I'm a bit unsure about this blouse - I am leaning towards 40s though. Would love some help! There are no tags (well there was a tag but it has since unraveled and I can't quite read what it says). Button closures down the back. No shoulder pads which is somewhat unusual maybe, but they could have been removed also. It's a cold rayon fabric. I was told 80s but it just doesn't seem to fit. There is some contrast stitching around the neckline. Thanks!
