I did have my doubts. Although many people seem to look good in the photos of their versions, the one on Grainline's site seems to pull a little under the arms, and...well that is not a very big-bosomed model. I need a C or D cup or I have to make an FBA. Still, I went ahead and made the purchase. I wasn't thinking straight.
I can't sew this up in good material. It needs adjusting, and I'm not sure how to adjust it. That vague memory of "clever construction" makes me think I can't do the usual. Maybe someday I will investigate to see if anyone has ever had similar problems and what they did about it. I suppose I could try a larger size at the top.
