So It was this Op:
Until it fell in my hands..
I shocked her with this photo XD
Then I started sewing. The dress came with a seperate waistband. So I used that as a waistband for the skirt. It was a simple job, I just had to regather the fabric and sew it to the waistband. There was a bow around the waistband, that I had to take off, and I turned that into a detachable bow with a pin in the back.
Here is the result. I like this alot better then the dress.
And because the bodice was to cute to throw away. I made a bag out of it.
I used the cuffs of the sleeves to make the shoulderstrap. That way I only had a very few scraps of fabric left over from this project.
Now I realy hope it will look good on her, well I am sure it will.
