I found this tutorial on Instructables and knew I had to try it right away. I made two - this dress, and a tunic top out of a smaller shirt. I used the belt to give it a little more shape but it looks really cute without it too. I added the t-shirt shrug for a more work-friendly look. That tutorial along with the one for the Scrabble necklace I'm wearing are available on my profile page!
I'm thinking about maybe adding some straps to this one... I'm not sure yet!
