One of our lovely readers recommended
Cross Designs to us. According to their website, it looks like they make a variety of clergy shirts, including features we've discussed like: T-shirt material, 3/4 sleeves, curved side panels, even cap sleeves. They don't have photographs, but you can see sketches of some pretty cute ladies' shirts (even maternity!)
here.
Prices aren't terrible, either. Even with the falling dollar, they seem to be under $100 each. I don't know how much shipping to the U.S. would cost. If anyone has a photograph of one of these shirts, we'd love to post it!
ETA: I looked more deeply on their website and found two photos, attached here:
