This is called the Nio Sweatshirt from All Saints. It is grey with a white hem.

The sleeves are full length. It is 100% cotton. The grey part is a normal sweatshirt material and the white frilled hem feels like a cotton shirt and sits really prettily below the sweatshirt

It is a size large but could be worn by different sizes depending on how you want it to fit.

The sweatshirt has only be worn once very lightly and is in really good clean condition
