• Small (S) Pocket Bra
• Large (L) Pocket Bra
• Extra Large (XL) Pocket Bra

Choose your Pocket Bra according to your current fit, rather than the breast size you hope to achieve. The Medium Pocket Bra in this kit is designed to accommodate all three included sizer volumes.

400cc vs. 450cc vs. 500cc: How Different Are They?

The difference between 400cc and 500cc is 100cc, or 25% more volume. The middle option, 450cc, provides a useful reference point between the two. Although these numbers describe volume, the visible differences depend on body proportions, existing breast tissue, implant dimensions, and surgical technique.

Oumènta external sizers allow you to explore three levels of fullness under your own clothing before discussing your preferences with your plastic surgeon.

400cc Breast Implant Sizers

400cc is the smallest volume in this kit. It provides a starting point for comparing a fuller external silhouette against the larger 450cc and 500cc options.

450cc Breast Implant Sizers

450cc is the middle volume, containing 12.5% more volume than 400cc. It lets you compare an intermediate level of fullness before moving to the largest option.

500cc Breast Implant Sizers

500cc is the largest volume in this kit, containing 25% more volume than 400cc. Comparing these two ends of the range can help you identify which external silhouette you prefer.

Does 50cc Make a Noticeable Difference?

A 50cc difference may appear subtle in some clothing and more noticeable in fitted garments. That's why it's useful to compare each volume in the same T-shirt, blouse, or dress.

Try the three sizes from different angles and during comfortable daily activities. The objective is to explore not only appearance but also your experience of additional external volume and weight.

What Cup Size Will 400cc, 450cc, or 500cc Give Me?

There is no universal conversion between implant cc volume and bra cup size. Your starting breast volume, chest dimensions, implant profile, and other anatomical factors influence surgical results. Bra cup sizes also vary between manufacturers.

Oumènta sizers help demonstrate external volume and appearance, but cannot predict postoperative cup size or surgical outcomes.

Why Compare Three Breast Implant Sizes?

Trying one size alone may leave you wondering whether a slightly smaller or larger volume would suit your preferences better. With three sizes, you can compare a smaller, middle, and larger reference point in the same Pocket Bra.

You can wear each size during normal activities for as long as feels comfortable and repeat the comparison over several days. This may help you clarify questions to discuss with your plastic surgeon.

Want an Intermediate Size?

Oumènta also offers 425cc and 475cc sizers. These intermediate volumes can help refine your comparison if you find yourself between two sizes.

How much bigger is 500cc than 400cc?

500cc contains 25% more volume than 400cc. The visible difference depends on body proportions, sizer placement, and clothing.

Is 450cc a good middle choice?

450cc falls halfway between 400cc and 500cc by volume. Trying all three can help you discover which external silhouette you prefer.

Can I use 500cc sizers in a Medium Pocket Bra?

Yes. The Medium Oumènta Pocket Bra in this kit accommodates all three included volumes: 400cc, 450cc, and 500cc.

How long should I wear each breast implant sizer size?

Try each size during comfortable everyday activities for as long as feels comfortable. You can repeat the comparison over multiple days rather than making your decision during one short session.

Can breast implant sizers predict my surgical results?

No. Oumènta sizers demonstrate external volume and appearance. They do not predict postoperative breast shape, cup size, or surgical outcomes.
