Hi! I'm new here. I have a gc2b medium half binder and a gc2b medium tank binder, but I always get the uniboob thing happening. It's my first binder, so I'm not sure if that always happens, or if there's anything to do about it. It fits otherwise, although the half binder sticks out under my chest at the bottom part where it's empty, so I'm considering cutting it shorter. I'm a B cup in bras, and I figure I have a medium sized chest. Had anybody else had a similar experience?
