Hi everyone! I'm going to be getting a pair of the New Simple 120 in patent leather and I wasn't sure if I should go more than a half size up. I unfortunately don't have the opportunity to go try them out in person but I was wondering if any of you have experienced stretching over time? Or if they're only a half size too small for me, could I just take them to a cobbler for stretching even if they're patent leather? Thanks so much!
