Those are all really nice, I might use the New Look one.
Here's the actual dress I was thinking of, isn't it cute?
I like how the neckline is curved instead of square. But what I'm concerned about (because I've never used a patterned fabric for some reason) is that with a pattern that has a lot of pieces, won't it be very difficult to line up the images right.
I'm sure someone has done this before. So I guess I also have to worry about how many pieces there are, and where they attach together.
