Thanks for the reply. I got the size that went with my inches, actually, I was on the larger end of the inches that this binder was for, so if it's too big for me, then their sizing guide is messed up, and I'd also hate to get a smaller size because I feel a ton of rib compression...
after a bit of messing around with it, I found a better way to situate myself than in this picture. I didn't mess with it as much when I took the picture because I wanted to get it off asap... for the sake of my nipples. I put it back on with a shirt underneath later, and fixed my chest, but once I was done, my nipples still hurt from scraping them the first time. Next time I put it on I'll have to be a lot more careful to cover them while pulling it on. I'd only had one binder before, but the material was much softer, so I hadn't even though of it. It did look a lot better when I tried the second time, but that little hanging part was still there, and I'm not sure if I should try to do something with it or what
