Is 375 Cc Too Big for my Small Frame?

Thanks for your question. Photos would be helpful. I would say that both sizes, a full or medium C, you mentioned are likely to achieve a solid augmentation. Based on your measurements, a final cup is better determined after performing an examination with a qualified plastic surgeon. Perhaps using a volume sizing system will help you feel more comfortable deciding from your choices. Silicone is known for being more natural when compared to saline. Be sure to consult with several surgeons and choose the one that best matches your goals.  It is always better to give yourself plenty of time to choose the best size and not rush to surgery. Best wishes, Dr. Aldo.

Based on your body description, I suspect that 375cc would not be too large. But there are many variables that go into how any breast implant size looks on anyone's body and there is the widely different and very personal interpretation of a good breast size and what constitutes a natural look. It would be a good idea to try on some sizers of different volumes before you make a final selection.
