Stylish wedding shoes for hard to find size

69196 Gr7216 Q. I am going to be married in the near future (we are considering eloping, so it's a bit casual). To that end, I picked up the J. Crew whitney silk faille dress in pale green and am trying to figure out how to accessorize it. I'm thinking strappy heels and some sort of wrap with dangly earrings, but I'm not sure what to do color-wise since the dress is a light sage green color and I don't particularly want to wear white with it. Would metallic sandals work? Where would I look for something like this (especially as I tend to need a 12W)?

Shopping for a larger size shoe can frustrating since many designers do not produce larger sizes and when they do, they produce fewer styles and stores buy smaller amounts of the styles compared to sizes 7 and 8. It may take a little more sleuthing to find a stylish heel that accompanies the chartreuse dress, but my suggestions lean towards a metallic heel and these shoe picks all come in your size:
