I'm looking for a pair of black kid rolandes (the sling backs) ... are they still avail? Any ideas on where I can find them. Even better if on sale (fat chance, I know). Also, can anyone give me sizing advice? I've heard size up half and size down half. I'm between a 39 and 39.5 in CLs usually. I have a pair of patent decolletes in a 40 which fit like a glove; however, I have a pair of slingback white mesh Mlle. Marchands that are a tidge snug in a 39. Should I stick with 39.5? TIA!!!
