Full C Cup Breast Implants Too Large for Petite Frame?

See this video of mine on choosing a breast implant:

Basically, this is the answer: don't think about cup size. It doesn't mean anything. If you want to look pretty and natural and not fake, then you need to simply pick the implant that fits you. You buy the shoes that fit your feet, right? So why wouldn't you get the breast implant that fits your breasts?

How big can someone with a petite frame go while still looking natural? The answer is different for everyone, depending on their body. Your doctor has to measure two things to answer this question.
Imagine lying on your back and drawing a circle around your breast. If you draw a line across that circle, it will be a given length. (The length of a circle is called a “diameter”.) This is a measurement that your plastic surgeon will take. The length of this area of your chest is called the “base width diameter” (BWD).
For women, the base width diameter ranges from 9.5 cm to 16.5 cm (3.75 inches to 6.5 inches). As you can see, there is a very wide range.
A smooth breast implant is circular, and has the same measurement as your BWD. So if your BWD is 12 cm, that tells us that your implant cannot be more than 12 cm. It won’t fit. So the BWD determines the max size of the implant, length-wise.
Then the question becomes, how much volume will this implant have? We’ve measured its length, now let’s measure how far out it will project. That projection is the Profile, which comes in low, moderate, full (high), extra full (extra high).
A moderate profile will fit into most women. For the implants with more volume, high and extra high, whether they will fit depends on how much your skin can stretch. The stretchiness of the skin is based on genetic factors, weight, age, and whether you have had children. A woman who has breastfed will have looser skin. That means it can be stretched further and have room for a high profile, if that is what she wants.
For the most part, the implant size and volume is limited by these two measurements: your base width diameter and how loose your skin is. It tells you how much you can max out on. As long as the breast implant is kept within these measurements, you will have a beautiful, natural look, even if you max out.
The “fake,” “top heavy” or “stripper” look happens when the patient wants an implant that is bigger than her measurements. If it does not fit her body, it will look unnatural. So as long as you stay within your measurements, you do not have to worry about looking fake.
I hope that answers your question on implant size. It’s great that you’re doing this research. I always say that the best patients are informed patients.
You might also want to research your options for breast implants. Choosing the right implant is the number one concern among women considering breast augmentation. Did you know, there’s actually a way to select a implant shape, size, and profile that is perfect for you?
A term that I use with my patients for the perfect implant is the “Pony Implant”.
So what do I mean by “perfect”? Well, a Pony Implant has three qualities to it. First, the implant meets your beauty goals. For example, you want to your breasts to look fuller while still appearing natural.
Second, when you chose your Pony Implant, you walk out of your consultation 100% confident that you’ve chosen the right shape and size for you. In other words, you won’t be second guessing your decision, and you won’t be afraid of having gone too big or too small.
And third, after your procedure, you are thrilled with your results, and say, "I’m so happy. This is exactly what I wanted!"
That’s the Pony Implant. And the great news is that there is a simple process to go about finding yours.
This issue of selecting the right implant is so important when it comes to patient satisfaction or dissatisfaction that, again, I really encourage you to learn more about it.
Thank you for reading and best of luck on your journey!

Patients should try on sizers before surgery to see what they like.  It is impossible to determine what your personal perception of the right size is without you trying the sizers on for yourself.
