I typically wear a medium shirt, I am 5'9" and 150 pds, 32DD. I previously ordered a large in this shirt since my belly is a bit bigger than normal, since Covid. However, the arm holes seemed too big, so I ordered a second one in medium. The medium is still slightly larger than a normal medium, and it does not fit tight around your belly, which is a plus. If you are debating between large and medium, honestly there was not a huge difference in the belly area, just the arm holes.See full review
