I redrafted my pattern making the bodice full length in both front and back. I also widened the sleeve, contoured the neckline, and added more fullness at the hips. Here's the new muslin.
I think it still needs more bust room so I've already done a tiny FBA to add one more pleat in the front nearest the armhole. I don't think I'm going to bother with another muslin. So, my next step is to cut out my fabric. I hope it turns out as cute as I think it will.
