Yup. Tortoise all the way. I believe these are two pumps in one. You can wear them when an outfit calls for a brown shoe... and also when an outfit calls for a black shoe. More bang for your buck.I agree. If I was going to do a brown patent I'd prefer the tortoise color also which is more unique looking but still in the brown color pallette.
I totally agree with the above posters that you should go with a patent tortoise shell brown. It will be a classic pair of shoes that you can wear for many seasons. Plus, they'll have more style than a pair of plain brown patents.
I saw your other pair in the Louboutin thread and they are so sexy. You need a brown pair to complement the black in your new collection. That way you'll be able to wear CLs with any outfit!
