You seem to have two very different concerns, namely implant size and whether to go with saline or silicone. To answer the first part of your question: It's impossible to say whether a 425cc implant would satisfy your beauty goals without getting a consultation first, and even then I would take care not to focus on cup sizes as a goal, especially for a woman with a larger skeletal frame.What's more, cup sizes are often inconsistent between different bras, even those made by the same brand. Also, keep in mind that you're not only getting an augmentation, but also a lift, which means your final result (and therefore your cup size) will also depend on the type of lift you get and the amount of skin removed. Even without the lift, the amount of cc's it takes to increase a cup size varies from one woman to another. In my experience, these factors along with several others make trying to predict cup sizes too difficult no matter how much time we spend during the consultation. This is why I suggest not aiming for a certain cup size and instead aiming for a certain breast size and shape. Now, for the second part of your question - when it comes to being undecided between saline vs. silicone implants, you're not alone. 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!
