450cc Breast Implant Sizers

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

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 450cc and other sizes over 400cc, for extra room.

You already own an Oumènta kit. Add 450cc to extend your range, or to compare it with the sizes you're already wearing.

You want to try 450cc at home in your own bra. If you mainly want to see how 450cc 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 450cc. Spend more time with the size before your consultation, through workdays, weekends, and different outfits.

You want to know how 450cc fits your routine. Wear it through the things you do every week, not just in front of a mirror.

Try the Sizes on Either Side. Compare 25cc steps with our 425cc and 475cc sizer pairs, or 50cc steps with our 400cc and 500cc pairs.

Compare Two Sizes Side by Side. Choose any two volumes with our Choose-Any-2 Sizer Kit, which includes a Pocket Bra.

Compare Three Sizes. Explore our 400cc vs. 450cc vs. 500cc 3-Pack or 350cc vs. 400cc vs. 450cc 3-Pack, or build a custom kit with any three sizes.

How 450cc Can Change Everyday Choices

Clothing fit. At larger volumes, fitted tops, button-up shirts, and dresses with a defined bust line may fit differently. Some women size up in tops; others change the styles they choose.

Bras and swimwear. A fuller bust can change which bras and swimsuits fit well and where you shop for them.

Activity. Running, jumping, and high-impact workouts can feel different with more volume. Notice how 450cc feels when you move, not just when you stand still.

How Does 450cc Compare With Nearby Sizes?

450cc has 12.5% more sizer volume than 400cc, and 500cc has about 11% more than 450cc. That doesn't mean your breasts will look 12.5% or 11% larger. The percentage describes the volume of the sizer, not your overall breast size.

Three Ways to Judge 450cc at Home

The closet test. Try on five pieces you wear often. Count how many still fit the way you like.

The workout test. Wear 450cc in a sports bra for a walk, a workout, or a busy day on your feet. Notice how the size feels in motion.

The relaxing-at-home test. Wear 450cc while you cook, sit on the couch, and lie down to read. Notice whether you stop thinking about it, or keep noticing it.

What Cup Size Is 450cc?

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.

Is 450cc a large breast implant size?

450cc is toward the larger end of commonly discussed implant volumes. How large it looks depends on your frame, chest width, and existing breast tissue. Wearing 450cc sizers shows you how it looks on you.

How much bigger is 450cc than 400cc?

450cc has 50cc more volume per breast, 12.5% more sizer volume than 400cc, or roughly 3.4 tablespoons per side.

Should I get 400cc or 450cc 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.

Can I wear 450cc 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.

Why buy a single pair instead of a kit?

A single pair is a good fit if you already own an Oumènta kit and want to add 450cc, or if you've narrowed your choice to this size. If you're still exploring, a 2-Pack or 3-Pack includes a Pocket Bra and lets you compare sizes side by side.

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.
