NWOT Best for a size small, labeled size medium White Lantern sleeve blouse made recently, but definitely gives a 40s look when paired with high waisted pants, or a pinafore Jumper and accessorized. There is no tag but it feels to me like polyester, it has six functional buttons, pleated, cropped and so elegant! Excuse the camera it has that “auto color Correction”, this blouse is a true white. Pls see measurements in photos I purchased this top on Etsy
