500cc Breast Implant Sizers

Drag the slider to compare the same model without sizers and wearing 500cc Oumènta sizers, our largest size.

Shown in the Oumènta Pocket Bra (bra not included with this pair). External sizing demonstration only. Not a prediction of surgical results.

For maximum discretion, we recommend the Oumènta Pocket Bra. Its internal pockets hold the sizers in place under your clothes, at work, at the gym, and out in public, and keep each size in the same position so your comparisons stay fair.

For trying the sizers at home, they can also be worn in a snug sports bra or a full-coverage bra.

Already own an Oumènta kit? Your Pocket Bra works with this pair. If you're buying a Pocket Bra with a kit, choose it by your current band size:

If you have a 32" band or smaller, choose Small (S) for 500cc and other sizes over 400cc, for extra room.

You already own an Oumènta kit. Add 500cc to see the top of the range, or to compare it with the sizes you're already wearing.

You want to try 500cc at home in your own bra. If you mainly want to see how 500cc looks at home, a single pair worn in your own sports bra or full-coverage bra may be all you need. If you'd also like to wear them out in public, a full-coverage bra or an Oumènta Pocket Bra you already own works best.

You've narrowed your choice to 500cc. Spend more time with the size before your consultation, through workdays, weekends, and different outfits.

You want to see the upper limit. Even if you expect to choose something smaller, wearing 500cc shows you what the largest option looks like and helps you decide where your size belongs.

How Does 500cc Compare With Smaller Sizes?

500cc has about 11% more sizer volume than 450cc and 25% more than 400cc. That doesn't mean your breasts will look 11% or 25% larger. The percentage describes the volume of the sizer, not your overall breast size.

Why 500cc Looks Different on Different Women

Your frame. On a taller or broader frame, 500cc can look full but proportionate. On a petite frame, it can look very prominent.

Your chest width. A wider chest spreads volume across more space; a narrow chest concentrates it.

Your existing breast tissue. 500cc added to very little tissue can look like a bigger change than 500cc added to a fuller starting size.

At larger volumes, your plastic surgeon will also consider your breast width, tissue, and implant profile when discussing what's realistic for your anatomy.

Three Ways to Judge 500cc at Home

The several-days-in-a-row test. Wear 500cc for several consecutive days rather than an hour here and there. Notice whether it starts to feel like you, or still feels like a costume.

The step-down test. If you own a kit, wear 500cc one day and 450cc the next. Notice whether you miss the extra volume or feel relieved without it.

The wardrobe test. Try on your everyday clothes, your work clothes, and your favorite going-out outfit. Notice which ones still work and which ones you'd need to replace.

What Cup Size Is 500cc?

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 big is 500cc?

500cc is 500 milliliters of volume per breast, the same as a half-liter water bottle. How big it looks depends on your frame, chest width, and existing breast tissue.

Is 500cc too big?

It depends on your body and the look you want. On some frames 500cc looks full but balanced; on others it looks very prominent. Wearing 500cc sizers for several days helps you judge, and your surgeon can advise on what your anatomy allows.

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.

Do you make sizers larger than 500cc?

500cc is our largest sizer. Our pairs range from 200cc to 500cc in 25cc steps.

Can I wear 500cc sizers without the Pocket Bra?

Yes. For trying them at home, the sizers can be worn in a snug sports bra or a full-coverage bra. For wearing them discreetly in public or through a full day, we recommend the Oumènta Pocket Bra.

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.
