I want bigger Boobs! I recently got 400cc and now I want 600cc or 650cc. Is 600cc to 650cc too big for me? (Photo)

I feel that at this point it's safe to assume that you can have 650cc easily inserted and not look "fake". The pocket has had time to expand to allow the bigger implants to be placed. Good luck

Thank you for the pictures as it helps us answer your
question.Going bigger is not always a
good option, as at times the soft tissues may not be able to support the larger
implant.I would recommend returning to your original plastic
surgeon and expressing your concerns and wishes.Based on your measurements, an appropriate
implant will be recommended.You can
always go bigger but have to consider the risks and benefits.Discuss these with your plastic surgeon.Good luck.

Thank you for the question and pictures. Based on your photographs, you are starting at a great place and should have a very nice outcome with revisionary breast augmentation surgery.  Given your concerns, “adjustment” of the breast implant capsules/pockets will  likely  play a role  during the revisionary breast surgery. In regards to specific size/profile of breast implant, despite good intentions, online consultants will not be able to provide you with  meaningful specific advice.  Ultimately, in person consultation with well experienced board-certified plastic surgeons will be necessary. Careful measurements, dimensional planning, and careful communication will be key.
Generally speaking, the best online advice I can give to ladies who are considering  revisionary breast augmentation surgery ( regarding breast implant size/profile selection) is:
1. Concentrate on choosing your plastic surgeon carefully.  Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.  
2.  Again, have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining which operation and/or breast implant size/type/profile will most likely help achieve your goals.
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or full DD cup" etc means different things to different people and therefore prove unhelpful.
 Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.  The use of computer imaging may be very helpful during this communication phase.
3.  Once you feel you have communicated your goals clearly,  allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals.  Again, in my practice, this decision is usually made during surgery.  The use of temporary intraoperative sizers with the patient in the upright position are very helpful.  I hope this, and the attached link (dedicated to revisionary breast surgery concerns) helps.
