The dress fabric is light blue with a white and dark-blue simplified sprig print:
The dress's scalloped neckline has dark blue narrow bias binding basted on:

This Aunt Grace Garden Party print is smaller scale but is a similar idea. If it's too small for a dress for me, maybe I could make a version for Jeannie.
