For a medium, the shirt is very small shown on a 35 inch bust mannequin and it is a snug fit. It is washed and air dried. Please note it is thin and there is under arm staining discoloration, which you won’t be able to see when you have it on because it’s tight and there are light yellow spots near the center front bottom, all shown in the last three pictures. 100% cotton see additional measurements in the pictures.
