Well some of that growth comes from the fact that I lost inches under the bust but nothing from the bust measurement but the important factor to also notice is that I was on a weight loss journey for a while and 30lbs is quite a substantial amount and despite this I still kept my bust at 39' (my underbust is now 29 so I've lost an inch from there since the last time I measured :O oooh!) before I lost weight my underbust was 34 and before I began using the right bra my bust measurement was 38! All in all it took me about a year to get where I am but it could be shorter if you don't have to lose weight. I wish I had taken before pictures but at the time I wasn't into NBE I only began researching NBE when I decided I want a phase 2 weight loss (goal 20-25lbs) and want to continue with my success in keeping the boobs 
Another thing I have not been able to find any nice and affordable bras in my size so I use 32F bra
In easter I'm going to buy a bust shaping thing and also one to wear while I sleep (they are big in Asia and I buy a ton of stuff from there so I've seen quite a few) so if you guys know any online store that seels good underwear I'd be really grateful to know 
I'll add a picture of how I look like currently ASAP (either later or latest monday!)
Here's the picture, sorry for the bad quality I had nowhere to put my phone so I had to take a side shot
I hope it gives you kind of an idea (although I think they look smaller than 39'.. sigh). Also do you guys think I have tuberous breasts?
