Rad True Vintage 1980’s Super Vivid Geo Print Silk Button Down Blouse

In excellent gently used vintage condition. One or two absolutely teeny microscopic spots, and very tiny tear / fray at one of the button holes, NOT noticable on, and still functions perfectly. See last few zoomed in pics for reference. No noticeable flaws while on. Tags have been cut out, so unsure of the brand or material content. Feels like silk, and the part of the tag that remains says wash on delicates only, so would assume it is silk, but obviously can’t say for sure. Has shoulder pads that can be removed. No size tag. Fits like a modern day L/XL. Listing as both, but there’s only one available. Please see exact measurements / feel free to ask questions to be sure of fit. Laying flat, Unstretched, and measuring across: Pit to pit: 23. 5” Waist: 22” Length: 26. 5”
