Vintage 90s Y2K mustard marigold silk blouse 1X

Vintage 90s Y2K mustard marigold blouse. 100% silk- not a silky texture, but flowy, lightweight & breathable, feels a lot like rayon. Front pockets, mother of pearl buttons down the front, notches at the sides. Has a boxy fit. Has one small light discoloration near the shoulder- seen in pics. Marked a 20W but vintage sizing varies from modern, so see measurements for a good fit- likely best for a modern 16 or 18. Measures (flat, unstretched, approximate): armpit to armpit: 26in, waist: 27in, hip: 27in, shoulder to hem: 28in, sleeve: 10.5in
