August Silk Sleeveless Tunic w/ Gathered Neckline and Self-Sash

Satin print front with gathered neckline that ties in the back. Multicolored print on white. Black knit back. Sash ties in back. Fabric content tag is missing but I do not believe it is silk. Approximate layflat measurements 22” pit to pit and 30” long. Size tag also missing so pay attention to measurements - I recall it being a size 1X.
