Ladies, I've been looking for the black back-zip Rolando/Bianca for quite some time now and sadly eBay turned up with nothing in my size. I'm a TTS M 6.5 in most brands and from what I read in the CL Sizing Info thread, I would most likely need a 35.5 Bianca and a 37 Rolando (don't want to risk the 36.5 as I read the toebox is extremely narrow... but I might if I absolutely had to). I've looked high and low across the internet for these sizes but came up short. Are the back-zips classic or are they now extinct? If they're always going to be around I figured I'd swing by my local Louboutin store and ask... but if they're not, any of you ladies know where to find them online? TIA!
