A picture of the Marc Jacobs, if you please my good sir, before you send them back. Couldn't you just put some insoles if they're a bit on the big side? They sound luscious.
I don't like fitting into larger shoes than I need to or I would keep them. They go perfectly with my white pants and white jeans among others. I've been buying too much brown, beige, and sand color shoes so this was a refreshing change for summer.
