Vintage 80s 90s 100% silk secretary blouse pleated bow black princess longsleeve

Vintage 80s 90s black (washed?) silk secretary blouse. It’s marked a size 10 but I have it listed as a small because it runs small. Please see the measurements and note I am modeling it in the photo and I typically wear a size 4. It’s a little billowy on me, but I like the fit. I think it could work for a size 6 or maybe an 8 as well. Beautiful blouse with asymmetrical hidden button placket, pleating detail down the front, pussybow tie / bow at neck, and pleated shoulders for a slightly puffy princess sleeve look. The buttons down the front and at the sleeve cuffs look like mother of pearl. Slightly sheer. Excellent vintage condition, this just doesn’t suit my lifestyle anymore. It’s been cleaned but could probably use a steam :) no flaws I can see. Brand is JACK MULQUEEN. Measurements are approximate and taken flat: Pit to pit: 19” Waist: 18.25” Length: 23” Tags: equestrian, office siren, work, classic, 70s, 1990s, 1980s, 1970s, retro, vtg, minimal, dressy, sophisticated, professional, classy, flowy, relaxed, effortless, feminine, button down, Paris, Ralph Lauren, Chloe, miu miu, Prada, Doen, quince, Ann Taylor, Ellen Tracy
