For the straps I forgot to take a picture, but I just used black gross-grain ribbon. I burned the edges with a lighter, so it wouldn't fray.
Here is what the finished project looked like. Paired with a black shirt, black tights, and black dress shoes. Miss Priss was all ready for church. This is probably my favorite thing I have sewed so far. I am still wishing it was in my size, but seeing Miss Priss and all her cuteness makes me not so jealous of her adorable new lace dress :>
