I know this is going to sound crazy, but I swear for about two hours the other day there was a Louboutin handbag on NM's (or maybe it was Bergdorf's) website. I was debating between it and the patent tortoise one at Saks when it disappeared. I couldn't believe my eyes. I know I wasn't dreaming. It wasn't the one you're considering, though.
Good luck finding it. It's pretty!
