so my SA called me today to ask whether ill be interested in a bi-color crocodile birkin which is coming to the boutique soon (black with fuchsia's piping and handle) instead of black birkin that i ordered.. I've been looking at photos of several bi-colors birkins on eBay and here in the forum.. i like them, BUT i'm afraid ill regret it once black crocodile birkin becomes available?? What do u guys think?? should i go for it?? or should i wait for a black crocodile?? how special/available are the bi-colors birkins??
