Visible difference between a 365cc and 415cc implant of the same profile?

Hello and thank you for your question. Honestly, a formal in-person evaluation would be needed to determine the best treatment. There are several reasons for this:
1) Bra sizes vary based on the clothing store (for example, Victoria's Secret tends to upsize everyone by a whole cup size)
2) Most women do not wear the proper exact fitting bra size for their bodies
3) The exact volume (in cc) needed to change cup size is different for different body types (e.g. 32A to 32D requires a different implant size than 38A to 38D)
4) Be careful NOT to fall into the trap most women do- they see a certain implant size (e.g. 285 cc) or perhaps their friend had a certain size, and they want or request this or another size based on that. Everyone's body is different- 285 cc implants on your friend might look VERY different than they would on you. Be very careful not to make this mistake, because the goal is to find the right size and shape for YOU- for your particular body and your breasts.

Because of those multiple factors, and because it is KEY to fully evaluate your breasts in person to make a full set of precise measurements to select the proper implant for you (incorporating factors like amount of breast tissue, implant type, base width, projection, etc), answering your question really would need a formal personalized consultation- to say anything before that would simply be guessing, which would be both unfair and unhelpful to you. Also, just FYI, each surgeon's measurements are slightly different, so numbers, experience, and overall aesthetic from one surgeon aren't necessarily the same as those from another surgeon!

Your breasts are such a KEY area of your body and your femininity- therefore, you should ONLY trust an experienced aesthetic plastic surgeon. As such an expert, I have had extensive training and experience with complex aesthetic surgeries under a multiple world-renowned experts in the field. I’d recommend for you to setup a formal consultation with me (or another plastic surgeon who is extremely comfortable with aesthetic plastic surgery procedures) for a formal consultation to thoroughly discuss your surgical goals, undergo a formal examination, evaluate all your options (surgical and nonsurgical), and decide on the best procedure(s) and type of anesthesia for your specific case. I hope this helps!

Yes, there is a difference of about one third breast cup in size between the two. This will be noticeable.

Hi, thank you for your question.
When it comes to breast implant size, when looking to increase the volume for a noticeable difference, such as going from a C cup to a D cup or D to a DD, I recommend increasing the volume by at least 100 grams, because the difference between 365 CC and 415 CC is minimal . When looking at the implant size chart, the difference between 365 CC and 415 CC is close to 3 mm of implant projection. So, if you are looking to increase volume, then you would need to be looking at 465cc to 480 cc depending on the brand of implant and their measurement chart. The ideal relationship between the thoracic diameter and hip diameter must be equal so, we can play with different volumes and projections compare it to your hip diameter versus your chest diameter and with the right size implants for your body, we can create that much desired hourglass figure. I hope this has been helpful, and I wish you the best.
