Dark gray blazer

I have used this for work in the past and layered over a rock T-shirt with jeans and sneakers.. have not worn in a long time it is in great condition. Tag says size 2 I am a small medium and it fits me perfect. I’m going to post it as a small medium you can go by the measurements tag sizes are not always correct. The material content is great in this piece. It even feels good. It is a blend of poly rayon and spandex. When you roll the sleeves up, it has the other material underneath the arm..2 buttons P to p almost 18 “ buttoned unstretched Length 23.5
