Kraken, I'm wondering if you can modify this binder? I've had to do that to mine before I found one that fits. I have a REALLY small rib cage so that even XS wouldn't do any proper binding. But I was able to sew it up in a way that made it fit better. Just make sure it isn't TOO tight of course. I found an Asian made binder that goes very small which ended up being almost perfect and lucky it was very cheap.
