This is McCall's 5484, an out of print pattern that I have sewn before, maybe 5 years ago, and that old dress is still one of my favorites. It always comes with me when traveling because it's versatile, unfussy and flattering, I think. I was actually wearing the old dress when I went to Mood on our trip to NY and one of the things I was looking for was fabric to make another one of these. So I picked up this rayon matte jersey which is beautiful, has a lovely drape, but it turns out is a bit too heavy for this style. In spite of my swayback adjustment that I had already worked out for my first dress, the fabric fell plumb straight away from my back because of its weight. I should have taken before and after pictures, but see this side view?
Imagine the fabric falling straight down from my shoulders to my butt instead of following the contours of my body. Not flattering, and not comfortable because of how it pulled down to the hem. The front is fine thanks to the under bust twist seam, and because I stabilized the neckline, but I had to come up with a creative solution for the back, so I added an elastic casing.
What do you think? I'm calling it a design element. The original design of the back is really quite boring without it anyway, and it does its job of keeping the dress snug against my back and taking some of the weight off the hem.
If you like green dresses, here's another one I sewed last spring: Classic Shirtdress
