I used Marian Martin pattern 9295. It was very roomy, so I think I ended up taking in about 3 inches from the front and back, and it's still really loose!
Sadly, the details do not show up very well (and yes, my posture is usually a lot worse than that). Silly quilting fabric with it's small print. Actually, silly me for using quilting fabric for a dress...
I really like the little square buttons.
I think I'm going to make this dress again, in a fabric I like! I did get up the nerves to wear it to the cottage school today. I got a lot of strange looks - it was really pretty funny!
