Mina perhonen laundry open front shirt

Arms are a bit short for me. Didn’t realize this is such a fancy brand, it was handed down to me from a friend. Not sure what the size is, I am a small or xs and arms are a bit short on me so I’m guessing xxs. A cool gray colour, soft corduroy, light jacket. https://www.mina-perhonen.jp/en/fashion/
