There are quality control issues with this top which is not surprising considering the price.  I normally wear a small but ordered medium based on feedback.  Out of 6 shirts, 2 were a little looser than the others and one v neck had a smaller v than the others.  I wish I had ordered large even though I rarely wear larger than a small.  You get what you pay for and since they were so inexpensive it is not worth returning them.  They are nice and long.
