100% Linen. Size tag says PETITE, but it fits similar to a LARGE. Or perhaps XL. Measures 20” across chest. Nice terracotta orange color (pic showing tag represents color the best). Great collar. This slightly flares out below waist like a peplum style. Very flattering. Wear closed like a blouse or opened as a 3 season lightweight jacket over another top. Good used condition….i never wear it anymore. Has an extra spare replacement button sewn inside. Could use washing - there is some slight dirt on cuff (not stained, just soiled).
