Need help securing my binder for a bigger chest

Ugh! I've had that issue FOREVER. Started with a large, and went down to a medium. I find if I hand wash them in cold water and dry them with heat (hanging up against a heater) they snap back into place, which helps a bit. I find my large size causes less adjustment, but doesn't look as flat imo

I wear underworks binders since i have a bigger chest and they work wonders! A bit cheaper too :)

I had to wear mine out for a few weeks before it got comfortable and broken in
