Oh, I'm SO jealous!!! I've always wanted a Read smocker. My smocking was limited to a few baby bonnets, years ago - before I had a BOY!
You might take a look at "Sew Beautiful" magazine. It usually has graphs for picture smocking - and frequently has garment patterns included in the magazine. They're frequently for children, but there are blouses and nightgowns periodically, as I remember. I've checked out back copies from my public library.
Enjoy!
