I am 165 cm tall and I weight around 53 kilos. My cup size is 32 B. I want to go two cups bigger. Any suggestions?

For a 2 cup size increase, I would consider a high profile round implant.  I suggest 3D  photographic analysis to make sure you are happy with this look.

There are important difference between shaped implants and round implants. This is particularly true with measurements that must be taken. Make sure your doctor has taken the appropriate measurements and allowed ample discussion with you. I spend a lot of time now with my breast implant discussion as the shaped implants from sientra have come into market because of how great they work. But they only work great in the right person with the right measurements and desires. Best wishes.
