Impossible Designs

Well, I was looking through the "VOTE FOR YOUR FAVOURITE" in stardesign when I found Impossible-looking designs. It really surprises me how all these people work their way around these things. But look closely at this picture:

See the thing in the middle of the dress? How did she do that? Also with the Jacket how on earth did she do that? You can't put multiple prints on designs so, I'm confused............

These designs look like the ones you would find in the designed by RC clothing!
