Utopia Care Women's Hospital Gown Soft Comfortable and Stylish Patient Gown

What is the fiber content?

I have never seen a 3 x large gown with a 26" bust/chest. this does not seem right. i thought a size body was 36", 24", 36". am i wrong?

could it be worn to snap in front as that is where I'll need access?

Do these zip at the shoulder?
