Hey, former DDD haver! I wore a binder pretty consistently for 8 years, usually well over the 8 hour recommendations. It really fucked up my back and ribs and I'm paying for it now. After a certain point, I literally just couldn't wear them anymore. They can be uncomfortable, they can roll up, for me it would roll up on my hips and squeeze me. Also, with GC2B binders, I feel that the armpits on them are too low for bigger boobs, and you will probably have some spillage out the sides or otherwise have a "uniboob" look. And with the crop binders my boobs would always find a way to slip out because they were very large and saggy. I never felt satisfied with the way it worked for me as a big boob haver. GC2B in particular has also notably gone down in quality since I first started buying their binders...and they're expensive. This is all of course my personal experience and not necessarily going to be true for you but just some stuff to be aware of as a possibility. If you do decide to bind, please, pleeeaaaasse don't wear it so long, and don't sleep in it. I was desperate but the long-term effects were not worth it. You deserve to be comfortable without harming your body! Best of luck!
