Yes, yes you can! I’ve lost 30 pounds and am about 5 lbs away from my target weight. My band size has gone down (from a 36 to a 32), but my boobs have stayed the same size. I’m happy about that though, since they weren’t all that big to begin with.
Now they look proportionally bigger than they did before, because the rest of me is smaller.

My understanding is that it depends on how much of the breast is breast tissue versus fat. If you have more fatty breasts, then yes your cup size should go down with weight loss. More breast tissue (ie - heavier, denser breasts) and they should not shrink with weight loss.
