Shoes

I need help finding a pair of shoes for my wedding. I feel like I have looked everywhere and came up with nothing. I am looking for a pair of flats. I am 5'8 and my FH is my height so heels are out of the question. I fell in love with Vera Wang Lavender Label Luna ballet flats but can not find them ANYWHERE!

Anyone have any ideas on where I can find a really nice pair of wedding flats in either a deep purple (eggplant) color or even a champagne (my dress is champagne)?? TIA
