SILK! Multicolor floral long-sleeve blouse brand & size unknown 100% silk

WHO DOESN’T LOVE THE FEEL OF SILK ON THE SKIN, SO COOL AND LUXURIOUS? AND WHEN IT’S THIS AFFORDABLE, WHY WEAR ANYTHING ELSE? THIS LOVELY PLUS-SIZE MULTICOLOR FLORAL 100% SILK LONG-SLEEVE BLOUSE is gently pre-owned, in near-perfect condition. It has no labels for brand and size, but it's otherwise free of defects, damage, or signs of wear. It features a lovely floral pattern, flowers and foliage in pastel tints of peach, green, pale purple (mauve?), and white on a sky-blue background. It has cuffed and slit sleeve ends with 1-button closures, a collar and minimal lapels if the top button isn't fastened, and a 6-button closure (with placket) in front. The buttons appear to be genuine mother of pearl (picture #12), but there's nothing on the label to verify this. There are 2 spare buttons attached on a tab next to the fabric-and-care label (picture #13). Machine wash cool delicate cycle, reshape, and dry flat are suggested, or dry clean. Since the size is unknown, we'll have to go by the measurements. Please compare them with those of a blouse that you know fits well. (Note also that it's a good fit on my mannequin Tonya who is 6'1" with measurements of 41.5" bust, 34.5" waist, and 43" hips.) Measurements are: chest, pit to pit 23.5"; no waist measurement, it's a straight 23.5" to the hemline; shoulder 22.5"; sleeve 20.5"; length (in back, collar seam to hem) 21". If you like the blouse but not the price, don’t despair, I’m willing to negotiate. Make me an offer.
