The 35" came off the tag. The measurements I am getting are 11"x11" for the front and back "shirt" part and 14" from top of collar to bottom of shirt. I assume it is one size fits most. Given to me by a friend from her mom's estate. She was a smaller woman. They would be great to get a layered look w/out all the bulk. I think only the black & white have been worn. All in new or great used condition.
