Compare Fuller Breast Implant Sizes at Home
Considering 400cc, 450cc, or 500cc breast implants? When you're exploring these larger volumes, a 50cc or 100cc difference may influence the silhouette you prefer. But photographs and implant measurements alone cannot tell you how each size will look under your own clothing.
The Oumènta Breast Implant Sizer Kit gives you three pairs of wearable breast implant sizers and an Extra Large pocket bra, so you can experience different volumes during everyday life. Compare the sizes at home, revisit your favorites, and discover which external fullness feels right for you.
What's Included in Your Oumènta Kit
1 Oumènta Pocket Bra in Extra Large
1 pair of 400cc breast implant sizers
1 pair of 450cc breast implant sizers
1 pair of 500cc breast implant sizers
400cc, 450cc, or 500cc: Three Levels of Fullness
400cc: The smallest volume in this kit. It provides a starting point for exploring a fuller external silhouette while allowing you to compare whether the additional volume of 450cc or 500cc is something you actually prefer.
450cc: Contains 12.5% more volume than 400cc. This middle option can help you determine whether an additional 50cc gives you the fullness you're looking for without moving directly to 500cc.
500cc: Contains 25% more volume than 400cc. Comparing these two sizes allows you to explore a meaningful difference in external fullness, clothing fit, and weight.
These are volume comparisons, not predictions of surgical results. Existing breast tissue, chest measurements, implant profile, dimensions, and surgical placement influence how breast implants ultimately look.
Does 500cc Look Different in Everyday Clothing?
Perhaps 500cc looks appealing in a before-and-after photograph. But will you prefer that volume when wearing your own wardrobe?
Start with 400cc in a fitted T-shirt. Switch to 450cc and compare the same outfit. Then try 500cc. Look at the silhouette from the front and side, and notice how each volume changes the appearance and fit of your clothing.
Repeat the comparison with a dress, a work blouse, or your favorite casual outfit. A size you love in one outfit may create a different impression in another.
Wear each size for as many days as you need. You don't have to decide after one try-on session.
Explore the Difference Between Looking Fuller and Feeling Comfortable
When you're choosing among 400cc, 450cc, and 500cc, appearance is only one part of the decision.
Walk, drive, carry groceries, or perform comfortable exercise while the sizers are securely positioned. Notice how the additional external volume and weight affect your experience.
For silicone implants, an additional 100cc of volume generally corresponds to approximately 100 grams of additional weight per implant, or about 200 grams (7 ounces) for a pair. Actual implant weights vary.
Oumènta sizers help you explore differences in external volume and weight, but they cannot reproduce the exact movement, weight distribution, or feel of surgically implanted breasts.

Why the Extra Large Pocket Bra Matters
The pocket bra holds the sizers in place so you can compare different volumes under your clothing. Choosing the correct pocket bra size helps provide a secure, comfortable fit during your home try-on.
An Extra Large pocket bra does not mean you need 500cc implants, nor does it indicate that a particular volume will be appropriate for your anatomy. Bra fit and implant selection are separate considerations.
Your plastic surgeon can help evaluate implant dimensions, tissue characteristics, and surgical options based on your individual goals.
Research Supports Comparing Breast 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.

Want to Compare 425cc or 475cc?
Sometimes the ideal comparison isn't limited to 50cc increments. Oumènta offers individual breast implant sizers in 25cc increments from 200cc to 500cc, allowing you to fine-tune your comparison with intermediate sizes such as 425cc and 475cc.
