Thank you for viewing! This is a GAP sweater. It's a thin knit fabric, 100% cotton. While it has been used, there are no frays or stains, so I think it can still be worn. It's convenient to wear over a school uniform or under a work suit. I think it can also be used as a spring knit. The color is light gray and the size is M. Here are the measurements, laid flat by a amateur, for reference ↓↓↓ Shoulder width: 44.5 cm Body width: 48.5 cm Length: 68 cm Sleeve length: 61 cm Please understand that this is a home-stored, used item. Thank you. m(_ _)m
