Is there anyway to get fuller breasts?

Not bigger, just fuller? Like I am an A cup. Trying to accept it. But I have this weird shape. Is there anyway to get like “fuller” breasts to get a little bit better of a shape? I heard that some firming creams/massages can give fuller appearances. Any thoughts? Or is this a pipe dream?

(I know plastic surgery is the only way to increase size. If I keep working out and lose any more breast tissue I will likely get a boob job but for now want to try to love my natural self)

Thanks for the tips!
