This is a Mizuno Little Senior umpire uniform. I purchased this on this site as a size L, but it was too wide, so I am selling it. I think it's probably O or XO. There was no size tag from the time of purchase. I will list it as size O. This is a used item. Please check the condition in the images and only purchase if you are satisfied.
