Gomme by Maki Hiroshige Atelier Co. of Japan. Purchased in Hong Kong. 90% cotton, 10% nylon charcoal French terry with slight stretch.  Super comfortable and drapes well as a layering piece with its assymetrical hem. Cute cotton/poly decorative florette black dots on front and mid-sleeve.  Size M but fits like a one-size since it is oversized. 

Because it is a material like a towel fabric, it has high heat retention and moisture retention, and is also excellent in water absorption.
You can wear it alone in the fall, and in the winter it won't feel stiff, so we recommend layering it.
It is very comfortable to wear
It is roomy and has a length that hides the hips, so you can cover your body 

23" long at "shortest part of front", 29" long at back, sleeve approx. 28" long. Wide and roomy and drapes nicely on any body type.

Rare and fabulous, comfy piece.
