Growing breasts by using bras.. What do you think?

I was reading an old post by fengshui who was a well known member who said by scooping breast tissue and holding it in place with an underwire bra can improve size.

What do you guys think? I know as per pics if I do that and keep adjusting it throughout the day I have a hugely improved cleavage with the almost zero body fat I have. It does however feel squashed and unnatural however I can manage to do so with my bra bands relatively loose.

Can that extra tissue in the cup stay there or encourage growth?
