OffOn Oversized Shirt with Revere Collar (Metallic Linen)

Oversized metallic linen shirt from OffOn, with the most beautiful shell buttons! There's no fabric tag in the shirt but the listing mentions: "Medium weight and 55% linen and 45% viscose Oeko-Tex certified fabric". It's in very good condition, didn't wear it much because it's not my style. Note there's no size tag, so please note the measurements I've included.
