I really love the back of the black and white dress! However I'm not too fond of the contrast of color. Of course that's just my opinion but if it was me, I'd dye the skirt. Maybe dark purple or black.
your skirt is absolutely beautiful! I love stuff like this because you can really tell how much effort the person (you in this case) put into it. Wear it proudly! it's really amazing! and I don't think I would ever have the patience to do this.
