I had to return this coat for a refund because the arm holes were much too small and it was too tight across the upper back.  And, I am not a large person, I have average size arms and shoulders.  The rest of the coat fit fine, and I loved the style and quality and feel of the fabric.  It seems to be the fashion these days to make clothes uncomfortably tight.  Coats are usually worn over heavier clothing such as sweaters or heavy shirts, and should havea loose enough fit in the arms to allow this.
