(Zana Bayne is a very recognized bondage designer. She has dressed the most daring celebrities: Nicky Minaj, Lady Gaga, Madonna and others)
Gwen is wearing this metal start cover over a black lace bodice, which I think looks beautiful and daring. Contrast is what I love and definitely this outfits makes its statement! I have posted a couple of Zana Bayne's design in this post. I am actually very inspired by her technique and probably will make a design of my own...but that's a different post ;-)
Below are some examples of her work.
