This 'Song' blouse is cut from lustrous moiré with dramatic leg-of-mutton sleeves and a fitted waist. The row of pearlescent buttons complement its 'Emerald' green hue beautifully. 51% Acetate 49% Cotton Size 6 I have worn and loved this blouse, ready for something new. There is one spot where the thread is bunched up, see photo. I would say Batsheva sizes run slightly small.
