Rare, vintage Iceberg Linus blouse

This Italian design house produced a limited edition of Charlie Brown apparel. This roomy, tunic is a goldish/creme color with a unique collar you can wear buttoned or not. Buttons down the front but the buttons are hidden. Cuffed sleeves. Is likely satin, but no legible material or size tag. In good condition though there is yellowing on the back of the collar. It measures, pit to pit 25, length 28. A rare find.
