Plain White Cotton Tunic

The product ordered was XL. The product received was more like a medium size (in Canada). I can barely put it on. It's way too tight. I am terrified to wash it, in case it shrinks more. The product is very tight across the shoulders, in the arms and across the upper chest. I have ordered similar products that were made in the USA by Indian families, and they fit me loosely and comfortably. The fabric in the photo looks like a lightweight cotton, but this top appearslike a medium weight linen, in a colour like ecru. This very tight tunic would fit a very petite woman or a child, rather than a grown woman like me. (And I am not obese.)
