Considering 400cc, 450cc, or 500cc breast implants? When comparing fuller volumes, even a 50cc difference can influence the silhouette you prefer. The Oumènta At-Home Breast Implant Sizer Kit lets you experience three external volumes under your own clothing before discussing your preferences with your plastic surgeon.
This kit includes 400cc, 450cc, and 500cc sizers, plus a Small Oumènta Pocket Bra. Instead of relying only on photographs or a few minutes in front of a mirror, you can live with different breast implant sizes during your normal activities. Compare how each volume looks in your favorite outfits, how the additional fullness feels, and which silhouette you prefer.
What's Included in Your Oumènta Kit?
- 1 Small (S) Oumènta Pocket Bra with internal sizer pockets
- 1 pair of 400cc breast implant sizers
- 1 pair of 450cc breast implant sizers
- 1 pair of 500cc breast implant sizers
Try each pair under your normal clothing, compare your silhouette from different angles, and wear each size for as long as feels comfortable. Repeat the comparison over several days if you wish. There's no need to rush your decision.

More About These Breast Implant Sizes
400cc vs. 450cc vs. 500cc Breast Implants: What's the Difference?
These three volumes cover a 100cc range, with 50cc increments between sizes. The 400cc pair is the smallest option, 450cc provides a middle reference point, and 500cc is the fullest. Comparing all three can help you decide how much external fullness you prefer.
400cc, 450cc, or 500cc: Three Levels of Fullness
400cc: A starting point for exploring a fuller external silhouette. Compare this volume with the larger options to see how your clothing fit and preferences change.
450cc: Contains 12.5% more volume than 400cc. This middle option helps you evaluate whether an additional 50cc creates the appearance you prefer without moving directly to 500cc.
500cc: Contains 25% more volume than 400cc. Comparing the two ends of this range lets you explore a meaningful difference in external fullness and clothing fit.
These percentages describe volume differences, not predicted changes in breast appearance. Existing breast tissue, chest dimensions, implant profile, and surgical placement influence surgical outcomes.
Can 500cc Sizers Fit in a Small Pocket Bra?
Yes. Oumènta's 500cc sizers can fit inside the Small Pocket Bra's internal pockets. You don't need to select a larger bra simply because you want to compare fuller sizer volumes. Choose your Pocket Bra according to your current fit, rather than your desired breast size.
Does 500cc Look Different in Everyday Clothing?
A size that looks appealing in a photograph may create a different impression under your own clothing. Start with 400cc in a fitted T-shirt, switch to 450cc, and then compare 500cc in the same outfit.
Look at your silhouette from the front, side, and three-quarter angles. Repeat the comparison with a dress, work blouse, or favorite casual outfit. Wear each size for as long as feels comfortable, and revisit your preferences over several days if you wish.
Explore the Difference Between Looking Fuller and Feeling Comfortable
When comparing 400cc, 450cc, and 500cc, appearance is only one part of the decision. Additional external volume and weight may also affect your experience during everyday activities.
Walk, sit, drive, or perform other comfortable activities while the sizers are securely positioned. Oumènta sizers can help you explore differences in external volume and weight, but they cannot reproduce the exact movement, weight distribution, or feel of surgically implanted breasts.
For a more detailed comparison, read our 400cc vs. 500cc breast implant guide.
Choosing Your Small Pocket Bra
The Small Oumènta Pocket Bra has internal pockets designed to hold the sizers in position. Using the same bra for all three volumes helps you make more consistent comparisons.
Choose the Small Pocket Bra based on your current fit, not the cup size you hope to achieve after surgery. If Small does not fit comfortably, explore the same kit with another Pocket Bra using the links above.
Research on Comparing Breast Implant Sizes Before Surgery
567 Women Studied
A published study involving 567 women examined preoperative breast implant sizing and reported an association between participation in sizing and greater satisfaction with implant size.
The study used silicone implant samples in bras, not Oumènta sizers. Its findings should not be interpreted as evidence that Oumènta products improve surgical outcomes.
