I took a chance when I purchased this product, and brought the top based on the material listed under the products details.  This combination of textiles should have produced a stretchier material.  The sleeves were too short, too small and too tight even for an XXL top.  The material was thinner than I expected and the only reason I won't return it is because it is too much hassle to do so and came in a box with several other items which I was pleased with. The sad part is, if only the arms were bigger the top should fit fine.

I am considering pulling the seam out on the sleeves and adding to the sleeve or cutting the sleeves completely off.
