This is a light, thin shirt. It's suitable for spring and autumn, and can also be worn in summer because it's made of a dry-touch material. It seems perfect for protection against air conditioning chills. I've worn it about three times and stored it at home. There's a stain of about 5mm on the lower left (see the last photo). It's not very noticeable, but please check the photo. Size (approximate measurements) Sleeve length: 53.5 cm Shoulder width: 40 cm Body width: 56 cm Length: 64 cm
