This is a top from Massimo Dutti. It's for spring and summer. The color is a versatile light gray. I've cut off the quality tag, so I don't have the details. It's a smooth, crisp material. It can be washed at home. The slit in the back is a key feature. Please refer to the photos for the length of the slit. I don't think the inner layer will be visible enough to be a concern. Size: M (fits like a Japanese L) Length: 60 cm Width: 53 cm I've probably worn it about 5 times.
