Hi Mimmi
Welcome.
I like Noogleberry, and if you email them, tell them a little bit about your self and what your looking for you will find them most helpful.
The domes come in various sizes so knowing your breast size ie what would be the diameter of the dome would be crucial.
If the total of the domes is bigger than the chest area you have then your not going anywhere.
There are other that work well also, I think its beautybudy, boosombuddy, or something in that area.
You can do a search in the suction section to get an idea.
The key to success is to keep doing it. and dont over do it. YOU CANNOT PULL A D CUP OUT IN A WEEK.
On average you need 200 hours of pumping before the the effect start to stay.
You will see more fullness than inches to your measurements, so dont be discouraged.
Taking pictures is a great idea to be able to gauge your progress.
Happy growing
Bobbi
