This is McCall's 6058, a pillow sack dress pattern that's reversible. The inside fabric I used is the same tan cotton blend that I used for my skirt. Since the pattern was for an infant, I made the largest size and added 6 inches to the length. It was really wide in the neckline when I used the elastic guide that came with the pattern, so I recut the elastic several inches shorter and redid that area. If I make this again I'll use the medium size with the added length. She's pretty tiny but this pattern is super wide.
I was careful to lay out the front and back so that the bottom black wave was uninterrupted, which you can see in the below picture. The side seams of this dress match as well, although some of the waves are a little cut up. That couldn't be helped since this dress has an a-line shape.
Instead of using fabric for the straps, I used 1" black petersham grosgrain ribbon, also from Mood Fabrics. Petersham is 100% rayon. It can be ironed into curves, unlike regular polyester grosgrain, and is just a better quality ribbon.
I have now successively used up all of this fabric. It's really fun to have a little person whose clothing doesn't take much yardage.
