350cc vs. 400cc vs. 450cc: Understanding the Differences

350cc: The smallest option in this kit. It provides a starting point for exploring moderate external fullness.

400cc: Contains approximately 14% more volume than 350cc. Comparing these two sizes can help you explore whether an additional 50cc changes your preferred silhouette.

450cc: Contains approximately 29% more volume than 350cc. This gives you an opportunity to compare a noticeably fuller external silhouette with the smaller options.

These percentages describe differences in volume, not guaranteed changes in cup size or postoperative appearance.

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.

Experience Different Sizes in Everyday Life

Begin with 350cc under a fitted T-shirt or blouse. Then try 400cc with the same clothing. Finally, compare 450cc.

Notice how your external silhouette changes while standing, walking, reaching forward, or performing comfortable everyday activities.

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.

What About 375cc or 425cc?

If 350cc seems a little too small and 400cc feels slightly too full, you can explore 375cc.

Likewise, 425cc offers an intermediate option between 400cc and 450cc.

Oumènta offers individual sizer pairs in 25cc increments from 200cc to 500cc.

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?

You can try suitable everyday activities, including walking and light exercise, provided the bra and sizers remain comfortable and secure. Stop if they shift or cause discomfort. 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.
