How Much Fullness Is Right for You?
Are you considering larger breast implants but wondering whether 400cc, 450cc, or 500cc would be the right choice? Perhaps you're excited about a fuller silhouette but concerned that 500cc might feel too large. Or maybe you're worried about choosing 400cc and later wishing you'd gone bigger.
The Oumènta Breast Implant Sizer Kit includes three pairs of wearable breast implant sizers and a Large pocket bra. Compare these volumes at home, under your own clothing, and explore how each size fits into your everyday life.
400cc vs. 450cc vs. 500cc: What's the Difference?
400cc: The smallest option in this kit, but still a substantial volume. It provides a starting point for women who want to explore a fuller silhouette without immediately choosing the largest option.
450cc: Offers 12.5% more volume than 400cc. This middle option helps you discover whether an additional 50cc creates the fullness you prefer.
500cc: The largest option in this kit, with 25% more volume than 400cc. Comparing these two sizes can help you explore a meaningful difference in external fullness, clothing fit, and weight.
These percentages describe volume differences, not predicted changes in cup size or surgical appearance. Your existing breast tissue, chest dimensions, implant profile, and placement all influence your eventual results.
What Does an Extra 100cc Really Feel Like?
When comparing 400cc and 500cc, the difference isn't limited to how your breasts might look in a photograph.
An additional 100cc of silicone implant volume corresponds to approximately 100 grams of additional weight per implant, or about 200 grams (7 ounces) for a pair. Actual implant weights vary, and Oumènta sizers do not reproduce the precise weight distribution or movement of implanted breasts.
Try 400cc while wearing a fitted blouse or T-shirt. Then switch to 450cc. Finally, compare 500cc with those same outfits.
Notice how the external fullness changes when you reach for the steering wheel, carry groceries, walk, or perform comfortable exercise with the sizers securely positioned.
Wear each size for as many days as you need. You might discover that 450cc provides the balance you're looking for—or that you genuinely prefer the additional fullness of 500cc.
What If You're Afraid of Choosing Too Small?
Choosing breast implant size can involve two competing concerns: going too big and wishing you'd gone bigger.
Perhaps 400cc initially seems like the sensible choice. But after spending time with 450cc and 500cc, you might discover that you prefer a fuller silhouette. Or you may find that the larger sizes aren't what you want for your everyday lifestyle.
The purpose of trying different sizes isn't to encourage you to choose larger implants. It's to help you explore your preferences before discussing your options with your plastic surgeon.
Research Supports Comparing Implant Sizes Before Surgery
567 Women Studied
In a published study involving 567 women, researchers found that women who participated in preoperative breast implant sizing reported greater satisfaction and were less likely to want a different implant size after surgery.
The study used silicone implant samples in bras, not Oumènta sizers, but its findings support the value of comparing sizes before surgery.
