So, I've recently found Burdastyle.com
and found these instructions on how to make a dress/shirt with no pattern- http://burdastyle.com/howto/show/65
and I did it! With the most gorgeous fabric I've ever seen (or close to it). I'm so happy!
It's a bit baggy, and the hem isn't even, but I wasn't going for perfection. It's kind of a thing where you do what fits best for you, so you can always bring it in easily, but I didn't.
I hope everyone else ventures into this project, too, as it's easy and fun!
