Vintage Shimmer Long Sleeve Holiday Sweater M

There are no tags to confirm true vintage however I have spent the last year learning to identify vintage clothing and the shoulder pads, feel of the material, quality and style lead me to believe this is from the late 80's to early 90"s. Very fun shimmery purple open front sweater. No size tag, I am a medium modeling in the last picture, would also fit a large. Would be really cute to wear on New Years or any holiday party. D
