Edward… This blouse does not have a size or material content tag… It feels like it's 100% linen, I'm sure it's Irish linen, as I have seen other Edwards listed with Irish linen… This is button front, short sleeve, has two front chest pockets, measures like a size M or L,,,, , please check my measurements to make sure this will work for you…

Measures about 22" across the armpit line…26" long...
