Honestly, those shoes are a bit over prices..I'd still say ebay will be fine, but search like, Orange pumps, or orange heels and you will get sone nice ones. You can actually just get a small piece of orange matching vinyl and make the ankle straps. Should look just fine. I DO know of someone that can make the outfit for you, but she's booked right now so f you don't need it really really soon, then I can throw her your way for you.
