450cc vs 500cc Breast Implant Sizers

Drag the slider to compare the same model without sizers and wearing 450cc Oumènta breast implant sizers.

External sizing demonstration only. Not a prediction of surgical results.

Choose your Pocket Bra by your current band size:

Because this kit includes sizes above 400cc, we recommend Small (S) rather than Extra Small (XS) if your band is 32" or smaller.

The Pocket Bra should feel snug and supportive, similar to a sports bra. A steady fit keeps both sizes in the same position, so your comparison stays fair.

450cc vs. 500cc Breast Implants: How Different Are They?

500cc has 50cc more volume per breast than 450cc. That's about 11% more sizer volume, or roughly 3.4 tablespoons per side.

That doesn't mean your breasts will look 11% larger. The percentage describes the volume of the sizer, not your overall breast size. How either volume looks on you depends on your existing breast tissue, chest width, and frame, and after surgery also on implant profile and placement.

Using Inspiration Photos the Right Way

Inspiration photos are useful, but not for picking a number. A woman in a photo may have a different height, frame, chest width, and starting breast size than you. Her 450cc may look nothing like your 450cc.

Instead, use your photos to define the look you want. Is it the roundness? The fullness at the top? The overall size compared with her shoulders and hips? Once you know what you like about the photo, wear each size and ask which one creates that look on your body.

How to Compare 450cc and 500cc at Home

Pick your three favorite inspiration photos. Write down one thing you like about each.

Recreate the outfit, if you can. If a photo shows a fitted top or swimsuit, wear something similar with each size.

Take your own photos. Match the angle of your inspiration photos, front or side, with the camera a few feet away.

Compare features, not bodies. Look at your photos next to your inspiration photos and ask which size captures the features you wrote down.

Bring both sets of photos to your consultation. They help your surgeon understand the look you want and talk with you about what's achievable for your body.

If You Land in Between

475cc sits exactly between these two sizes. If 450cc feels slightly too modest and 500cc slightly too much, compare 475cc with 450cc in a 25cc 2-Pack, or build a custom kit with all three. If both sizes feel like more than you want, try 400cc.

At the top of the range, your surgeon's assessment of your measurements becomes especially important. For a wider look at larger sizes, read 350cc vs. 450cc Breast Implants: Which Size Is Right?

Will 450cc or 500cc Give Me a DD Cup or Larger?

There's no reliable conversion between implant volume and cup size. The same volume can look different on two women, and cup sizes vary between bra brands. Oumènta sizers show you external volume under clothing; they can't predict your cup size after surgery.

Why Try Sizes Before Surgery?

In a published study of 567 women, a group who tried silicone implant samples in a bra before surgery generally reported that the preoperative sizing process was helpful. The study used implant samples, not Oumènta sizers, and doesn't show that Oumènta products affect surgical outcomes.

How much bigger is 500cc than 450cc?

500cc has 50cc more volume per breast, about 11% more than 450cc. The difference is often visible in fitted clothing, swimwear, and from the side.

What is the largest Oumènta sizer?

500cc is the largest size Oumènta offers. Individual sizer pairs are available from 200cc to 500cc in 25cc steps.

Why doesn't my body look like my inspiration photos at the same size?

Frame, chest width, existing breast tissue, and implant profile all affect how a volume looks. That's why trying sizes on your own body is more useful than matching a number from a photo.

Which Pocket Bra should I choose if my band is 32" or smaller?

Choose Small (S). Because this kit includes sizes above 400cc, we recommend Small rather than Extra Small for bands of 32" or smaller.

Should I get 450cc or 500cc breast implants?

That's a decision for you and your plastic surgeon. Wearing both sizes at home can help you understand which look you prefer. Your surgeon will assess your anatomy and recommend implant dimensions that suit you.

Will these sizers show me how my implants will look?

No. Oumènta sizers show external volume under clothing. They can't reproduce implant placement, tissue response, implant profile, or surgical results.
