Green silk short sleeve dress

This piece has no tags indicating brand, size or material. It looks, feels, and behaves just like my other 100% silk items…I have two pieces that I am comparing it to. No stretch at all. Has pockets, no lining, no tie belt (has the loops on the waistband) front pocket with button, three buttons on front up to the neckline with one small fastener at the top. No stains or marks, it’s like new. Measurements - shoulders and sleeves are my best guess because of the cut of the fabric panels, there’s no shoulder hem from which to measure. Shoulder to shoulder: ~20” Pit to pit: 19” Waist: 18” Sleeve opening at shoulder: ~11” Cuff opening: 5.5” Length from shoulder: 42” Length from waistband: 25”
