350cc vs. 400cc vs. 450cc Breast Implant Sizes: Experience the Difference
Is 350cc enough to give you the fuller figure you want? Would 400cc offer the right balance, or will you wish you'd chosen 450cc?
Compare our 350cc, 400cc, and 450cc breast implant sizers to discover which size you prefer.
The difference between 350cc and 400cc is just 50cc, but moving from 350cc to 450cc represents nearly 29% more volume. For a woman seeking a noticeably fuller silhouette, that difference may be important.
It's not just how different these sizes look. It's how you feel wearing them.
Go for a run, lift weights at the gym, reach for your steering wheel, or carry groceries. Does 350cc feel comfortable and proportionate? Does 400cc give you the fullness you imagined? Or does 450cc feel like the size you've always wanted?

Consider the Additional Weight
A 100cc increase in silicone implant volume represents approximately 200 grams (7 ounces) of additional weight for a pair, although actual weights vary. How might that additional fullness and weight feel during exercise or everyday activities? Oumènta sizers help you explore those differences, although they don't exactly reproduce actual implants.
Wear each size for as long as it takes to decide. Compare how they look under clothing, how they feel when you move, and which size you prefer.
Don't just imagine the difference. Live with it.

Click any question to see the answer.
How noticeable is the difference between 350cc and 400cc?
A 50cc increase represents approximately 14% more volume than 350cc. The visual difference may be subtle, but you might notice changes in fullness when wearing fitted clothing, reaching forward, or exercising. Your body proportions and existing breast tissue also influence how different implant volumes may look.
Is 450cc too big for my body?
Not necessarily. Your frame, existing breast tissue, and personal goals all matter. A 450cc implant may create a more noticeable change than 350cc. Trying Oumènta sizers at home can help you explore your preferences before discussing implant suitability with your surgeon.
How much more does 450cc weigh than 350cc?
For silicone implants, a 100cc increase generally adds approximately 100 grams per implant, or about 200 grams (7 ounces) for a pair. Actual weights vary by implant construction and materials. Oumènta sizers allow you to explore additional fullness and weight, although they do not exactly reproduce actual implants.
Can I exercise while wearing Oumènta breast implant sizers?
Yes, you can try suitable everyday activities, including walking, light exercise, and lifting weights, provided the bra and sizers remain comfortable and secure. Notice how different sizes feel during movement, but remember that external sizers do not behave exactly like surgically implanted breast implants.
Will 350cc, 400cc, or 450cc sizers show my exact results after surgery?
No. Oumènta sizers help you experience different breast volumes under clothing, but they cannot predict your surgical results. Implant profile, placement, existing breast tissue, and individual anatomy all influence your final appearance. Always consult a qualified plastic surgeon.
Important: Oumènta sizers are wearable, experiential sizing aids—not medical devices or actual breast implants. They do not predict surgical results or reproduce the exact weight, shape, movement, or feel of implanted breast implants. Always consult a qualified plastic surgeon before making surgical decisions.
