Blue aqua 3/4 sleeve top by Marshall Fields is 95% silk and 5% spandex and is NWOT. The fabric is a heavier feel than comparing to thin silk fabric. There is a scoop neck and 3/4 sleeves. From the middle of the shoulder down to the hem is 21” (in my opinion this length is more like a petite). From armpit to armpit seam unstretched is 18” across. True vintage Marshall Fields (I bought at the store years ago, I miss Fields!). Hand wash. Made in China.
