I recently saw an old Burda knitting & crocheting magazine from the 1970sโand a couple of their patterns were as form-fitting as your top.
Checked the instructions to see if the garments had dart-equivalents*, et voilร : They had!
I do enjoy it when these forgotten/neglected techniques get new attention, so thanks for your efforts!
* instructions included how to shape the garment to achieve the 3D effect darts would have if these were sewn garments
