This pattern is McCall's M5619; I made it out of a cotton fabric that one of my friends alerted me to. She made knitting project bags out of it, and when she gave me one, I said, "I should make a dress out of this!" So I did. Then I wore it to church.
I did the short sleeve version, added pockets, and took in the bustline a little bit (I'm a size 14 for nearly all proportions except the distance between my shoulders and bust, which is shorter than the patterns think it ought to be). This is my first dress in a long time, and my dress completely unaided. My grandmother taught me to sew, and she usually did the interfacing bits--I don't remember doing much of it. But now I can.
Oh, and if anyone's curious, the shawl I'm wearing in the picture is "Miralda's Shawl," pattern by Nancy Bush, from Knitted Lace of Estonia. It's in my projects on Ravelry (where I'm Winnifred17), if you're interested.
