I was told that the best way to get cleavage was to have overs rather than unders..
I’m not sure about the low profiles – maybe they have a wider circumference so they end up closer together than the high profiles. But its true that they wont look as big and juicy as the high profile ones.
To be honest though, i think it all depends how close together your boobs are to start with – implants cannot work total miracles unfortunately.
So if you’re natural boobs are far apart,, your fakeys will be too.
But a good push-up plunge bra will soon sort that out once you’ve got some melons to squash! xx
