275cc Breast Implant Sizers

Drag the slider to compare the same model without sizers and wearing 250cc Oumènta sizers. 275cc adds 25cc of volume per side to the size shown here.

Shown: 250cc sizers 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. That matters most when you're comparing sizes only 25cc apart.

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 own a kit with 250cc and 300cc. If one felt slightly too small and the other slightly too full, add 275cc to try the middle.

You want to try 275cc at home in your own bra. If you mainly want to see how 275cc 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 275cc. Spend more time with the size before your consultation, through workdays, weekends, and different outfits.

Try the Sizes on Either Side. Compare 25cc steps with our 250cc and 300cc sizer pairs, or 50cc steps with our 225cc and 325cc pairs.

How Different Is 275cc From 300cc?

300cc has about 9% more sizer volume than 275cc, and 275cc has 10% more than 250cc. That doesn't mean your breasts will look 9% or 10% different. The percentage describes the volume of the sizer, not your overall breast size.

A 25cc step can be subtle. Some women see it clearly in fitted clothing or from the side. Others notice it more in how a top or dress fits than in the mirror. How visible it is depends on your frame, chest width, and existing breast tissue.

When "Slightly Less" Is the Right Answer

Your clothes fit the way you want. If 300cc made your favorite tops or dresses feel a little tight across the chest, notice whether 275cc fits more comfortably.

You want to feel like yourself. Ask whether the size feels like a natural part of you after a few days, or like something you're still getting used to.

Your side view. Take matching front and side photos in the same outfit and lighting. Small differences often show most clearly in profile.

Worried About Regretting Your Size?

Choosing between two close sizes can bring up the fear of going too big or too small. For more on that decision, read 275cc vs. 375cc: Will You Regret Going Too Big or Too Small?

What Cup Size Is 275cc?

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 275cc noticeably smaller than 300cc?

275cc has 25cc less volume per breast than 300cc, about 1.7 tablespoons per side. Some women can see the difference in fitted clothing or from the side; others notice it mainly in how their clothes fit.

Should I get 275cc or 300cc 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.

Is 275cc a natural-looking size?

It depends on your body. On some frames, 275cc looks modest; on others, it looks fuller. Wearing 275cc sizers under your own clothes shows you how it looks on you.

Can I wear 275cc 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 275cc, 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.
