350cc Breast Implant Sizers

Drag the slider to compare the same model without sizers and wearing 350cc 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:

You already own an Oumènta kit. Add 350cc to fill a gap in your range, or to compare it with the sizes you're already wearing.

You want to try 350cc at home in your own bra. If you mainly want to see how 350cc 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 350cc. Spend more time with the size before your consultation, through workdays, weekends, and different outfits.

You have a cup size in mind. Wear 350cc in the bras and tops you own and see whether it gives you the look you're picturing.

Try the Sizes on Either Side. Compare 25cc steps with our 325cc and 375cc sizer pairs, or 50cc steps with our 300cc and 400cc pairs.

Compare Two Sizes Side by Side. Try our 300cc vs. 350cc 2-Pack, 350cc vs. 400cc 2-Pack, 325cc vs. 350cc 2-Pack, or 350cc vs. 375cc 2-Pack, each with a Pocket Bra.

Compare Three Sizes. Explore our 300cc vs. 350cc vs. 400cc 3-Pack, 250cc vs. 300cc vs. 350cc 3-Pack, or 350cc vs. 400cc vs. 450cc 3-Pack, or build a custom kit with any three sizes.

Why 350cc Doesn't Equal One Cup Size

Cup size is relative to band size. A cup letter describes the difference between your band and the fullest part of your bust. A D cup on a 32" band holds less volume than a D cup on a 38" band, so 350cc can fill those two bras very differently.

Brands size differently. The same breasts can fit a C in one brand and a D in another. A cup letter isn't a fixed measurement.

Your starting point matters. 350cc added to an A cup and 350cc added to a full B cup produce different results, and existing breast tissue, chest width, and frame all change how the volume sits.

After surgery, implant profile and placement also affect how a given volume looks. Your plastic surgeon will assess these with you.

How Does 350cc Compare With Nearby Sizes?

350cc has about 17% more sizer volume than 300cc, and 400cc has about 14% more than 350cc. That doesn't mean your breasts will look 17% or 14% larger. The percentage describes the volume of the sizer, not your overall breast size.

Three Ways to Judge 350cc at Home

Your favorite bra test. Try 350cc in a bra you own and like. Notice whether it fills the cup the way you'd hoped, or spills over it.

The dress test. Put on a fitted dress or a top with a defined bust line. Does the fit look the way you picture yourself after surgery?

The full-day test. Wear 350cc from morning to evening. Notice how the size feels by the end of the day, not just in the first few minutes.

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.

What cup size is 350cc?

There's no fixed answer. Cup size depends on your band size, bra brand, and starting breast size, so 350cc can fit different cup sizes on different women. Wearing 350cc sizers in your own bras shows you how it fits on you.

Will 350cc give me a D cup?

It might for some women and not for others. Your band size, chest width, and existing breast tissue all affect the result. Your plastic surgeon can discuss what's realistic for your anatomy.

Should I get 350cc or 400cc 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 350cc 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 350cc, 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.
