Looking for advice on GC2B binders for small chested trans/nonbinary folks

I use GC2B binders. It helps, but it's not perfect. Back before I started binding, I wore G-cup bras. I just assumed that I still had a busty chest because my breasts were too big to flatten completely. I still get dysphoria about my chest when I wear my binders, but not as much as I do without them.

It's been a few years, I got top surgery in 2019, but I had DDs and it worked fairly well. At that size a little bit of a bulge is expected but all considered it got me pretty flat and smaller chests are easier to bind.

It was a long time ago but I have a large chest and used to bind with a gc2b binder - I found that after a short time it stopped binding as well and it didn't really get much use. I remember even though it was the right fit and I was wearing it for the right amount of time I would get pain in my ribs, eventually I started using spectrum outfitters instead
